The pub I work in actually charges you a five pound deposit if you want to take a glass outside. It's a mad policy, and something I totally disagree with. Also if you want a litre stein it's ten pound deposit. Sure, they are unique glasses but surely there weren't that many going missing...
Theres a pub in Manchester who have a supply of crocs behind the bar and if you order a beer with decent glass (usually something Belgian like Orval etc) then you have to give them a shoe as a deposit.
They found people would just treat it as paying for the glass if it was a monetary deposit and they're the type of bar who self the beer in the proper glass so always found themselves short.
