I can understand why she did not know. Weight was probably taught at primary school and referred to as grams and kilos so no need for an abbreviation and would have no knowledge of lbs.
Very few people buy loose items by weight and certainly not a 20year old.
I dare say that a 20-year-old knows a lot more about tech and things relevant to the younger people's world today than I do so I would not be critical going down the young people today route.
Me too. It's not 'young people' - things other than fashion trends are very rarely confined to one generation. If I said 'older people today - intolerant and condescending' I'd expect to be told off for stereotyping, and this is no different. 'A kilo' looks and sounds different from '1kg', and the girl was just checking rather than get it wrong. No doubt she would have been castigated if she'd just gone ahead and used the wrong quantity of hazardous substance.
Speaking of older people - back in the day I went to a newsagent to pay my paper bill, and the assistant (older than I was at the time, but I was young) looked flustered. The papers were 25p each and I handed over £1 to pay for three. He got the back of a receipt and wrote
25
25+
25
_
75
then
100-
75
_
25
and counted out my 25p change. If I was 25 and he was 50, I guess he'd have been at school in the 40s.
