Sounds like a small thing but it really pissed me off!
I have two friends that I often meet up with as a group of 3. We all get on well, no one gets left out, and I like them both. Whenever we meet up for coffee, meals or drinks out, I'm always first to offer to pay for all three of us. I'd say I pay for all three of us more than a third of the time. I feel like I've also been a good friend to the other two in many ways. Both can be quite self absorbed.
On Saturday the three of us went shopping together. We went into a coffee shop to get a drink and something to eat. It was the kind of shop where you queue at the counter, choose your food and then they get it ready for you to take over to your table. I suppose how places like Costa do things too.
My friends were ahead of me in the queue. Friend 1 asked friend 2 what she wanted to eat and drink. The order was then prepared, Friend 1 paid for the two of them then they just grabbed the tray and went off together to a table over the far side of the coffee shop, out of view. There was no asking me if I wanted anything and neither said 'oh we'll just be over there LuLu'. It was as if I wasn't there.
I didn't say anything as it seemed too ridiculous in itself to say something but the more I've thought about it the more I think it was really quite rude of them and inconsiderate. I just ordered and paid for my own drink and then went and found them at their table but of course by the time I got there they were deep in conversation.
Like I said before, it seems like a small thing but it's annoyed me and just seems like they didn't consider me at all.
