They also struggle to use a till/calculator. On our recent trip I bought a burger and 3 coffees and it came to around 11.70. Handed over 15.00 then stood in amazement as the young lady first tried to fathom out the till, then asked another worker for a calculator that didn't seem to work (doesn't everyone have a phone these days with a calculator?). Eventually she managed to work out I was due 3.30 in change and thankfully the coffee was at least still lukewarm by the time she did.
