Slim Chickens UK interview questions

Welcomed and asked to take a seat in the restaurant, manager came over and had the interview in the restaurant which is okay. Manager asked questions and wrote down any important things

Solely a run-of-the-mill job interview. The first question I was asked by the female interviewer: 'What age are you?' (Which is UNLAWFUL to ask and IS age discrimination). Long story short: I completed the interview, but was certainly not interested to work for this company anymore.
