Honestly, I've sat down for a cup of tea and a bloke has sat at the next table and is on his phone ranting at his bank or credit card company. He's really angry, making no attempt to be discreet and is now on call two to them. He's coming across as quite unpleasant and this is spoiling what could be a relaxing few minutes. Grrr. AIBU that he needn't do this publicly?
