Is there a key on the card payment machine which cancels the charity donation which seems to be charged every time my elderly friend shops?

Easy if you can see clearly the SKIP on the screen!! This option should be pointed out by the cashier... if you're unaware due to disability or elderly, then this is basically theft by Bashas for taking money the customer does not know about until it's too late! Great store, but has some worrying faults that the manager should address.

Skip...

Yes, just press skip
