Douchebag shop attendants/owners.
Went to one of those set up store things in the middle of the shops where you'd get shoes/watches repaired etc (in this instance I needed shoelaces). I said to the guy, I need a pair of shoelaces for standard dress shoes. His response straight away was "there's no such thing as a standard dress shoe.". I'm like 'uh OK, well I need shoe laces." He responds with "how long? 75cm, 90cm, 100cm?" I said I'll take the 75cm length, he hands me one. And goes to put the others back. Then I said, you know what, I'll grab the 90cm as well. He started laughing like a smug bastard and threw his hands up in the air and chuckled. I pulled out my card to pay. Minimum eftpost limit. Just what I want to hear.. Tell him I will go and get cash out cos I don't have cash.
Went and found a shoe shop that sold laces for cheaper and without a douchebag worker.
While I could have been a bit more informative, he acted like a ******* dick.
