I like strong tea. I was in Costa at Tesco's in Colchester. I ordered a tea and asked if they could put an extra teabag in as I like it strong - tea can be very anaemic in cafes sometimes. This request isn't usually an issue.
"Yes" said the girl. I paid £1.50 and moved over to where the barrista girl was working. She looked - gormlessly at my order as my turn came, then announced, "Sorry, I can't give you an extra tea bag without charging you twice."
"Really?!" I answered, thinking "....£1.50 for just another teabag; fuck off!!!"
I'd already paid; had some time to kill, so I stayed and had my drink.
It was anaemic.
