Sorry, have name-changed. Relatively new relationship, we went to the chinese last night and it was kind of pre-arranged that we'd just each buy our own. When we got there the place was really busy so I looked at what mine cost (£3.60) and gave him this amount exactly and told him to just get both to save time. He then counted it up and said "everything on the menu has gone up 30p" and stood there actually wanting the 30p. We'd agreed to buy our own but isn't it going a bit far to actually ask for the extra 30p?!
