I've come across Les Dennis and Amanda .... her surname escapes me but it was his ex-wife. She was genuinely lovely but he just looked miserable although it was Sunday morning and they (she!) was clothes shopping.
Footballer Nigel Winterbourne (sp?) was another one who was who I was once served in a shop, no airs and grace despite being asked for his signature when he was trying to pay for goods! And one of his card was declined!
