is this the same in all greggs? i find it hard to believe that perhaps the biggest chain of bakers in the country doesn't process debit cards.
i don't know about you, but i never carry any more than a couple of quid in change around with me (unless i have a specific reason), i pay for almost everything with plastic because it's easier. i can understand them having a minimum transaction value for cards (like you can't pay for a 80p bag of rolls on your card), but when you go in for a bite to eat with 3 or 4 people with drinks that's going to be 15-20 quid.
anyway, i left the food and had this instead:

yummy yummy. loads better than a jacket potato.
