I dont carry much cash around with me and its very rare i use my debit card too, but you know the times when you have that few quid in your pocket and you think i want that, and the next minute your pockets empty,
Then within hours you need something else, and another thing and before you know it you have spent your cash and you are at the ATM getting out some more,
These days dont happen very often i am glad to say and why cannot cash machines just give out a fiver or bring back the old ten bob note
