Tony Robinson has small man syndrome and was really rude to train staff and the general public. Basically wanted a carriage to himself.
Michael McIntyre, Nick Knowles, Lawrence Luellen-Bowen are all horrible people and are super rude to grocery store staff. Very stuck up. Especially Nick.
On the nice end, Ben Miller is absolutely wonderful! Such a gentleman. Served coffee for him many times.
John O Shea signed an autograph for me many years ago and he was really really nice.
Jude Bellingham and his dad are really nice people and very down to earth.
Edit: I forgot about Gary Stringer lead singer of Reef. Met him at a small acoustic gig with just him and his guitarist. Had a long chat and shook hands before wishing each other a good night and going separate ways.
