local farm puts eggs out for sale and has an honesty box. Eggs are £1.70. We mostly use card/cashless and so sometimes have exact change but often only have £5 note or £1 or £2 coins.
do you think you should only buy with exact change? Is it acceptable to put £2 in and then pay slightly less next time? Put £5 in and take next one free and put in 10p next time?
I assume they don’t want wastage but also don’t want to be short changed! What do you think is reasonable?
