It’s often said that one of the major advantages to playing online bingo is in its convenience – there’s no need to get dressed up if you’re not going out. When you’re sitting in front of your computer you can get away with just wearing your pyjamas and letting your hair fall wherever it’s comfortable. However, you might feel different about Posh Bingo. Squeeze into your classiest ballgown, do your hair real nice like, and put your Lambert and Butler in a diamante-studded holder. Yes, we’re talking a different class of online bingo – one that uses “summer” as a verb, that probably has a second site registered in the French Riviera, and that has a butler called Jeeves who irons its copy of the Financial Times every morning.
