Die besten Restaurants mit Vietnamesisches restaurant Essen in Kandern

When I went into the restaurant, the waitress always looked at me rudely, without asking any questions, just looked rude, until I first asked if it was free. I sat down at a table, then the waitress walked up to me and stopped briefly on the way and showed no desire to serve me, of course I didn't accept such behavior and ordered nothing and left. This is my worst experience at the Asian restaurant, I'll ask if she's too German too, if I'll be treated like that with an Asian face? As an Asian person, I find it very uncomfortable at such Asian restaurants
