Is this the most expensive international airport ever?

Passing through Istanbul we changed flights leaving the International and moving to the Domestic terminal. With an hour to spare until our connection we chose to have a beer apiece and share a bag of crisps.

Unbelievably two local draught beers and the crisps came to US$ 17

I have been to some expensive resorts and extortionist night clubs where drinks can be pricey but in a snack bar at the airport I think this is pretty outrageous

I am wondering, is this the most expensive airport beer?

Have you experienced higher prices?

Do let me know
