To be annoyed I gave up my seat on train

[NameChangedJune]

4 hour journey, late train so pretty empty carriage, most seats unreserved.
i take a seat on an empty table of 4 which has a laptop charger.

before train moves, a family get on (there are loads of empty twin seats but no empty table), but say they are a group of 3 and a baby them, do I mind moving from the table so they can have the table to lie the baby on?! They say they have reserved the seats but the seats themselves say unreserved. I see they have a small baby so say fine and close my laptop and move to a twin seat (now have no table or laptop charger).

the three adults (couple and I assume grandparent), and baby sit on the table. Baby doesn’t settle so after a few mins mum takes baby to another free twin seat to feed and they both settle to sleep there. The father then move to another empty double seat nearby and sleeps. This leaves the sleeping grandparent taking up the entire table with feet up on the seat opposite (plus a few baby bits/scattered about).

AIBU to now be annoyed I gave up the table and the chance to catch up on work as the other tables don’t have power sockets?

Yeah I'd have found that annoying. One of those things!

I'm so confused. Lay the baby on the table??

I am now 70+. I have learned not to do favours like this any more. You can’t blame the people you made the sacrifice for. You can only blame yourself. Chalk it up to experience and don’t do it again.

I would have moved back anyway 🤷‍♀️

It would have annoyed me too, you did the kind thing and it's clear they didn't really need the table.
I think waking up single person remaining on table for 4 and saying as they no longer need the space you need it back so you can charge, laptop, meet a deadline would have been fine- if no other tables or chargers were available, equally saying no I'm sorry I need to work in first instance would have been fine.

I had similar type of situation last week at a village fete at tea tent elderly couple with walking sticks came over and asked if our 2 empty chairs were taken , I said they were actually for my husband and daughter who were in the queue but said do take them if you need to sit down - they then carried seats to a large family group of adults and children and proceeded to go round collecting chairs from other tables so their whole family group young and old had a seat!! Clearly counting on sympathy card to get people to give up chairs, very cheeky !

As they say no good deed goes unpunished😂
