Popped into Brownlows to buy two locking nuts 13mm...

Popped into Brownlows to buy two locking nuts 13mm and one grub bolt. These would cost around 9c each for the nuts in the Co Op superstore and 25c for the bolt, but I needed them straight away and Brownlows was near by.
They charged 2 and thats fine no problem.
But when I went to pay by card as I did not have change the guy serving me told me it was ridiculous to come to a shop and not to be able to pay and had a good rant, firstly I did pay, secondly it's the 21st century most people don't carry cash.
The visa debit service charge for this transaction would be 0.1% which I would have happily paid even though I had been well over charged anyhow, yet this ignorant man thinks its ok to be ignorant and rude to a customer over 0.1% from a 2 sale!
Put a notice up if you don't accept card under a certain value and don't be so ignorant! The transaction fee was well covered having been well over charged for 3 nuts! I'll go elsewhere in the future. They seem to forget I spent 200 on a tool set the week before never again! Avoid!
Unless of course you like being spoken to like a piece of s##t! I have delt with some of the other lads in here and there grand, but this curly grey haired ignorant tw#t needs to learn some manners!
