Years ago, when I first moved to America from the UK, I was working in a pretty quiet office that backed on to a field. One day mouse appeared, freaked out a couple of the gals in the office, and then it ran and hid under an office cube.
I investigated to see where it was hiding, but it was pretty dark down there. So I asked if either of the gals had a torch. They both got an expression of wide-eyed horror, which confused me for a few seconds.
Then I realized that torch had a different term in America. So I corrected myself and asked if either of them had a flashlight. And they looked very relieved. They thought I was going to get an old school torch and try to smoke the mouse out or set it on fire, and probably set the whole cube on fire in the process.
I was in North Carolina for work recently and one lady was talking about her local brewery where she could "grab her growler" and head over there.
Took me a while to recover from laughing at that one.
Only Growler I have is from a brewpub that doesn't exist anymore. They did gangbusters business in a walkable downtown area selling pints over the bar. They decided to move across town to the part where pedestrians never go to focus on retail sales of packaged beer and were out of business within 6 months.
Not a single Jonathan who has been through the UK school system in the past forty years has gotten away with being asked “Have you got a rubber, Johnny?”
