This could go in PBIDMHI, but I thought I'd put it here since it's appropriate.
Yesterday I lost my hat going through security at Stansted (it was 6am and I'd been on a coach since 1, allow it) so when I realized I was missing it I went back to the x-ray machines and asked if anyone had seen it. One young woman was quite helpful but the following also occurred, which wasn't:
me: I think I lost my hat while I came through here earlier, could you have a look for me?
stupid security bitch: have you checked in your bag?
me: it's definitely not in my bag, can you please have a look for me?
SSB: but have you checked?
me: ...
Because I might have stuffed a fedora into already bulging backpack that doesn't have room left for a baseball cap, let alone a broad-rimmed hat, and then forgotten I'd done it. Obviously.
(happy ending because I later rang them and it's in lost property, so phew)
