mini-bars

Why are prices in a hotel mini-bar so expensive?

So what's a mini-bar?

It's a small fridge in your hotel room, in which different drinks, peanuts, chocolate and possibly something else are kept.

Even if you eat something from mini-bar, the next day it's full again.

So it's quite easy to grab a pack of crisps from the fridge and don't worry about going to the shop.

Consequently, the demand on goods in mini-bar is usually inelastic and the administration of the hotel make prices on this goods very high so they can make a profit from it.
