Was out with the Missus and on the menu was a bottle of Dom Perignon for $1,550. A quick Google and I see that I can buy my own elsewhere for $160. They also had Absolut Vodka for $400 ($23 retail).
Now, obviously there is some real value in this. I mean, do you really want some amateur doofus - a mere service industry employee - pouring your drinks? Of course not! If you want something done right, you have to do it yourself.
