Die besten Restaurants mit Sandwichladen Essen in Alsfeld

I went into the store and politely asked if I could use the restroom. However, I was told quite rudely that this was only for customers. I then offered to buy three cookies, but I was still insulted again and told again that the toilet was for customers only. I don't understand why I'm not considered a customer despite my intention to purchase. Ultimately I just left. I have rarely seen such an unfriendly employee.
