De Waag in Doesburg is the oldest catering facility in the Netherlands and is listed in the Guinness Book of Records.
De Waag used to be directly involved in trade.

In the time of the Hanseatic League, traders had to pay tax to the city of Doesburg on the goods they brought into the city. At that time, it was based on weight. The coin they paid with was weighed with another coin, a kind of test coin, on the scales. This happened in the Waag. If the weight did not match, the coin was not only made of gold and had been tampered with. If it turns out that there had been tampering, the person was punished. The punishment could be different but was generally painful. It could literally cost you your finger.

The tenant of the Waag also had a monopoly on the sale of foreign beers in the city. At that time people did not drink ordinary water. The water was not cleaned and it contained many germs. Beer was therefore the popular drink in the 15th century because brewing made beer safe to drink. At that time, beer did not have such a high alcohol content as it does today. But the higher your position was, the more percentages of alcohol you had in your beer. If you were in jail, you were out of luck. Then your beer consisted of more water with a little alcohol.
