Someone said they paid 5 bucks for a beer. This is how to prevent that: walk into the bar. go to bartender. say Een Pils please/alsjublieft they might ask something, say Small/kleine you will receive a glass of beer, about the size of of a cafeteria water glass. It'll probably cost you two euro. Hope this helps
Yeah they usually ask "how big is your cock" at the bars I go to....but I guess your answer is correct anyway.
