I wasnt in the mood to cook tonight dh was out and it was just me and the kids so we decided to have a take away went to fish and chips shop was served by a very polite I would estimate 16-17 year old whom took my order and then said that will be £11.90 I handed her £22 and at this point the chip shop owner stepped closer to her and said "seeing you how gave wrong change yesterday with the £10 now be careful today" She went "I dont know how to do that I dont know how much I need to give her back" I was quite shocked and just said "£10.10" but after i was thinking this is really not a hard piece of math and I would expect someone working in a shop to be able to do a piece of math like that in their head. at the dinner table I asked my lot whom could do it asking them to put their hand up in the air once they had it all bar dd3 (age 6) could do it within 1 min ds and dn (8 and 16) doing it within max 10 seconds.. (ds being a bit of a math wiz I did expect him to be able to that fast) dd2 whom struggles in school was the longest (age 10 ) but still got it within the minute..
So I am obviously aware that this girl could have had issues but I find it quite that she wasnt able to do this if she worked in a fish and chips shop (she isnt new Ive seen her there before she has been working there for a while)
I did ask cant the till do that for you?"+ and she went no but the owner went well yes so perhaps once I left she was taught how to use the till in that way
