...so that he could 'get to work'?
I am not sure if I as being unreasonable to feel this way. I had dropped my DC off at school and had my other young DC with me in the pushchair. We had run out of basics that morning (due to DP eating them late at night 
) such as bread, butter, milk etc) and so I had had to prioritise giving DS his weetabix with the last of the milk and make his sandwich with the one remaining slice of bread. I then took DS to school and went straight to the coop for said basic things. Neither myself nor DD had had a proper breakfast, just a banana and a drink of water each to tide us over, and I hadn't had my coffee (which is why I am asking if IWBU). Anyway, the plan was to get home and make proper breakfast for us before heading back out again on various errands.
When I reached the counter and put down my basket, the shop assistant nodded at the man behind me and said to me "Can I just serve this man behind you first luv, because he has got to go to work?" I was a bit grumpy I'll admit, and gave her a bit of an incredulous kind of look and said something along the lines of yes I would because he only had a few things, but in my head I was quite hacked off and thought she shouldn't assume that I wasn't in a hurry to get somewhere (In truth, I was...my caffeine-deprived, low blood sugar self was really wanting to get back home and eat!). She seemed sheepish, and tried to make small talk when she was serving me about my shopping. The man behind me had a can of red bull and a meal deal. He looked very apologetic. He hadn't asked to go in front - I assume he comes in on his way to work quite regularly and the woman took it upon herself to ask for him.
Now, if the man himself had asked if he could jump in front because he was running very late (for example) I would have probably agreed, but I didn't like the way that this woman was implying that my time had less value than his. I felt that she made assumptions that because I was in there at 9:15 with a toddler that I was not in a hurry perhaps, but I feel like it wasn't her call to make really. I am in there a lot as it is probably the closest convenience store that takes cards and is open long hours.
So WIBU? Was I right to feel a bit put out or was it just my lack of coffee and breakfast making me over-cranky? (Please be kind as it is my first AIBU 
).
