. . . . . . if you ask for mayo on your salami salad sandwich they put the mayo on the salad side not the meat side ?
The dozy bints who make my sandwiches do this so often it really irks me. Mayo is clearly the salad accompaniment and it also serves to stick hold the salad in the sandwich so it doesn't all drop out - SURELY EVERYONE KNOWS THIS so why would you spread mayo on one side and then stick the meat on top of it???!!

. . . . . . . . . and relax.
and surely carpetted professional (ish) offices generally operate a no dogs policy?
Used to work in an office on first floor - client was coming up to see me on the first floor - receptionist told him to "go up and Mr Howard will meet you at the top of the stairs". As i head towards stairs I can hear this really heavy breathing getting more and more strained - poor old bugger I think - bad emphysemia that. I am then met by Staffordshire Pit Bull straining at the leash to get up stairs ahead of owner

I was too shocked to say get your stinking dog out of here so i just got on with the appointment asap while the dog lounged on my nice carpetted floor. The receptionist said "oh well there isn't a sign saying "no dogs" so I thought they were allowed"
Anything else that dimwits have done that make you think "is it just me but surely it goes without saying doesn't it. . . . .?"
