Maybe he pissed someone off, i have seen many people with tatts in First and even some fat guy with a naked girl on his arm!
When i checked in other day wearing this t shirt i was told to cover it up while in the lounge i forgot what it said when i left the house! but the CSD in First said Nice T shirt cant please everyone. i ended up in this t 3 days in row after BA lost my case on way from BCN
