Shop came while WFH

Sounds like you both have bigger issues than shopping deliveries to be concerned about.

But it's not two minutes though and even if it was "only" two minutes it was two minutes during Bs work day when the OP has no idea if B could afford to step away from work for those two minutes.

In the end it worked out fine in that B was able to do it but I hate people presuming they have any kind of claim on my time - if I'm at work then you should not expect that I can just walk away from what I'm doing at any given moment - sometimes I might be able to walk away and other times I 100% can't but I don't know myself when those times are so you can't assume I'm free, but if you give me prior notice (IE "Delivery is due between 10-11, I should be home but, just in case I'm not, are you OK to bring it in?") then I will do my best to make sure I'm not doing a "can't walk away" task unless/until the other person is home and/or the delivery has arrived.

B had no notice of the delivery coming so when the door went they probably thought it was the postman or OP had forgotten keys or something so they would be away from their desk for a minute or two ... Instead they had to deal with the grocery delivery which will have taken a minimum of 5 mins to actually accept (answer the door, confirm delivery, empty totes (and/or wait for driver to bring entire shop from van), return totes to driver, and bring it all in. B may have had a free minute to take a parcel/let OP in but did not have the 5-10 mins to spare at that moment to accept the groceries, but once they'd opened the door and realised what it was then they could hardly close it again and ignore the driver at that point, which is probably what annoyed them more, especially as the OP could have told them at any point "Hey I booked the food shop delivery for this morning" even just as an FYI.

A is unreasonable. They booked the slot and should have been home. Could have been problematic for B if on calls, deadline etc.

Life is too short…

Surely life is too short for this crap.

What’s the real issue in your relationship?

Is this a real post 😂 it is so trivial not even worth thinking about

Changed my mind. B is wrong to not let it go. It’s a storm in a tea cup. Easily solved with ‘ Yeah sorry about that, thanks for getting it in and putting those bits away.’
‘ No worries but I might not always be free to do that, just so you know.’

The person ordering the food should order it for a time they’re going to be there, or at least arrange a suitable time with the other

Is B going to eat this food? If yes, then B needs to STFU.

B was trying to be helpful and probably wanted a bit of acknowledgement for the unexpected inconvenience. Did A swan in and not mention it?

This. Honestly, what a fuss over nothing!

Also, B didn't have to put the frozens away, surely they would have been fine for a few minutes until A arrived home.

A polite mention would've been good. Finding out if B had a meeting that would be disturbed by a delivery would've been good too. I think B was nice to put things away.

What’s really going on in your relationship? This stand off isn’t about putting shopping away.

Someone might have nicked it

Depends on what their job involves.

This. It would be really awkward in my job if the doorbell was going and I knew it was a food delivery and I had to stop and get it.

A is in the wrong. B took the shop in and unpack the frozen stuff. What’s wrong with that?

It depends.

working from home means different things depending on the job.

if you are in an important meeting, on a one to one call, delivering a presentation, teaching a class you can’t excuse yourself to put away a grocery shop - it’s highly unprofessional and to be frank to shop would get ignored.

if you are writing a report or managing emails etc with no meeting scheduled then it’s no big deal.

I could be doing either - presenting online to 200 people or just catching up on emails.

If B had a business call with colleagues at 10am then maybe he has a point. Otherwise, this is all a bunch of petty foolish fluff that doesn’t matter. B should be thankful that he gets to work from home and that the groceries get delivered without him having to do anything except put frozen stuff in the freezer. Big whoop.

B needs to have a word with themselves. 2 minutes, if that, to put freezer stuff away is hardly a huge distraction. I'm sure they think they're very important at work but doubt they'd be missed for 2 minutes.

B needs to get a grip and realise A can't control every single thing. I'm sure B would soon be moaning if there was no shopping in for the weekend.

B is being a dick and A needs to divorce them, this does not seem like a good relationship

I’m quite surprised by some of these replies tbh.

B sounds like they completely overreacted.

A should not have been home late but these things happen.

Its not As fault that they didn’t send a text.

I suppose A could have sent a text saying they’d be late but there was no point if the shopping wasn’t due (or so they thought because they hadn’t had the text yet).

He should have been the one to apologise to you first.

I wish this was all I had to worry about in my life, I would be living the dream….

I think A & B needs to get a grip of reality.
to actually come on here to ask this question and even spend time on this is ridiculous.

how do people have head space to even think about this kind of thing!!!
