Ooh my first ever AIBU. I must be in a masochistic mood 
I went to Ikea on Friday (perhaps that's an AIBU all on its own haha). I was by myself and at 8 months' pregnant I needed some assistance with getting a chest of drawers into my car.
When I paid the 12 year old young chap at the till said 'there'll be someone downstairs waiting to help you'. I got downstairs after a rather lengthy wait for the lift and couldn't see anyone who looked like they might be there to help. After wandering around for a while with a trolley that wanted to go in the opposite direction to me and cursing the boy upstairs for getting it wrong, I eventually spotted an Ikea employee standing at the exit to one of the lifts, not the one I'd been in, on the opposite side to where I'd exited.
I approached him and said 'Excuse me, could you help me get this to my car' to which I received the rather stroppy reply that he'd been waiting there for me for 5 minutes. Somewhat taken aback by his tone, I said sorry no-one had told me where I had to go when I got downstairs, just that someone would be waiting for me and i hadn't seen him. He replied that he'd been told I WAS told where to go. At this point I was starting to think he was a little rude to push the point, as it was obvious I hadn't deliberately kept him waiting!
Anyway, he told me to go and get my car and bring it round. After backing up I opened the boot for him and waited. It all went quiet. I couldn't see him as my view was obscured by the open tailgate. So I got out to ask if all was OK and he was just standing there. He said "Well i don't want to hit the back of your car with the trolley so I need you to put your foot on it while I pick up the box." "Well why the fuck didn't you say so instead of standing there like a lemon expecting me to be psychic?" would have been my preferred reply but being terribly British about it I compliantly put my foot on the trolley and he put the box in the boot.
I thanked him but what I really felt like saying was "your customer service skills need a bit of work mate". AIBU and overly-hormonal or was he a bit of an arse? Mumsnet, it's over to you!
