Anyone have a nice passive aggressive reply to this rudeness?

[Shouldbeworkingnotreadingtalk]

Last sent a text on Thursday arranging for collection of an item I'm selling. Have had various texts over the course of the week. Item value is £32 if relevant.

Last text them on Thursday to say text me and I'll send directions. (This photo shows a Google message thread, I don't have their phone number) ... Just walked in the kitchen and these ping through.... am slightly hungry, so feel a bit hangry. It's also Friday and I'm rushing to visit a friend in a minute. Absolutely want to say "don't bother - you rude twat". . As I can't stand the ??? After them not getting an immediate reply. However, I'd prefer a passive aggressive reply if anyone got any smart ones?
Unfortunately I've already replied with a no problem - postcode attached, see you Sunday, but would also quite fancy pulling them up on their rudeness. . Talk me off the ledge? ... if relevant I don't need the £32 but would be nice to get rid of the item. Thoughts? Am I being an unreasonable hangry person?

Just an update for everyone - the customer actually came and collected today and I'm so pleased I was talked off the ledge. He was LOVELY!! ... and was driven here by his mum ... I think maybe a little shy (?) or neurodiverse (?) so definitely I think the "?" Wasn't him being rude.
Im very pleased for the wise MN words if advice. Thank you all very very much.

If this is the explanation, their batshit out of control anxiety isn't OP's problem and they shouldn't put it on her like this.

It's rude to ignore a message string for a day then suddenly reply out of the blue and send a nudge ? when the OP doesn't dance to their tune 15 minutes later.

Glad it was all ok in the end.

Glad it was OK but I'm amazed only one other person on the thread noticed the lack of a very important word, which is please. That would have annoyed me and I'd have responded:

Please find the postcode noted below. Thank you very much for for asking so nicely.
