I start as a waitress in a weeks time at this lakeside pub near where I live in the UK. (16F) The interview went well except my boss mentioned that im quite quiet and that it can get very busy in the summer when I'll be working. Im quite a reserved and shy person and did have a waitressing job last summer but only in a small cafe, and my boss mentioned then to other workers that she thought i was unenthusiastic because i was quiet. I also suffer from social anxiety and anxiety a lot, so im worried i wont do well in the job and will be too quiet and get fired.

Any tips or advice on how to improve my confidence or anything like that will be greatly appreciated
