I guess we better get back on topic.
Now!! Here's a (perhaps) legal argument for you all. Kegs have the name of the brewery stamped on them, as do milk crates. My friend and I were having a few quiet brews at the local Belgian, and we began talking about the glasses, and how pubs give out glasses with tapped beverages.
I purchased a Leffe Brune, mate purchased a Leffe Blonde. Barman washed some Leffe glasses, filled them, cut them, etc. and eventually handed us 2 glasses full of tasty beverage. We handed over some precious currency and the deal was done. We paid money for beer, we were given a beer in a glass (a very nice one at that).
Mate decided to put the glass in his bag as we left, barman came out as we left, noticed only 1 glass on the table and requested the other glass off my mate, who reluctantly gave it back.
I thought about it after. No, there were no signs explaining the glasses belong to the bar. No, the barman didn't say "these are our glasses don't take them off the premises". If I bought a blender at a store, am I required to send the box back so they can put another blender in it and sell it? Nope.
Would've loved to have argued the point with the guy but I was too busy trying not to laugh at my mate as he pulled a Leffe glass out his bag in the middle of the street.
Should all of this "guilt" about using brewery-owned kegs and milk crates be applied to pilfered-glasses as well?
