A public 'restroom' is the last place one would want to 'rest'. They usually smell awful. Deposit and go.

I wonder if the expression 'a can of worms' is US or UK? I've never heard 'a tin of worms'.

My old dad was in the RAF and always used 'kite' for an aeroplane. I don't know if this was general or just one of his eccentricities.

I believe if one is 'pissed' in USA one is a bit cross, not inebriated.

They also call a pet cat a 'kitty' not a 'pussy' like us. Perhaps that's rather wise...
