Burger King in Frankfurt am Main

Long waiting around 30 min for a burger. I wanted to eat in, but they put everything in take out.

The chicken kebab was very bad. The fries weren't warm and the chicken kebabs couldn't even be called chicken kebabs. Actually, it wasn't worthy of eating.

It is 9 AM in the morning and some breakfast items are not available I wasted four minutes online to Order

We have never been treated so disrespectfully! It says "please wait to be seated" at the entrance. We waited there for 10 minutes, the waitress looked at us several times but ignored us completely. Meanwhile, the last table was occupied by someone else who didn't follow the rules and simply bypassed the sign at the entrance. For this reason, we went to the waitress to ask what was going on, i.e. why they made us stand there for 10 minutes and instead served the guests who simply walked past the sign. She then said that the board is just there and if there is no space for it, she doesn't care, it doesn't interest her. I have never experienced such incompetent and disrespectful service. No apologies, just cheeky answers. And that's only because we stuck to the sign they put up. Really outrageous!

Completely crazy staff booked vouchers incorrectly. I didn't feel like complaining in real time because explanatory communication was probably only possible with hand and foot signals.
