I can understand in your day to day cafe, a selection of 5 teas is normal and to the person behind the counter when you order a pot of chai, you are really only ordering 'tea' to them.

In a boutique tea house where there is a wide range of teas on selection, where you expect them to have some background knowledge in the range. Does it become Tea snobbery to be annoyed when the waiter brings you a fruit infusion because they were out of Chai?

Arthur Dent had just had his home destroyed, followed by earths destruction for a hyperspace bypass. He found hinself on board a dushbags ship, with the girl he loves dating that dushbag, and to top this all off when all he wanted was a cup of tea, he ended up with a cup of mud.
