Unprofessional staff

I had a really unpleasant experience.While I was eating upstairs there were four staff members speaking loudly and behaving in a way that felt unprofessional and disruptive.What made it worse was that one of them kept loudly snorting mucus repeatedly😭😭 with no apology or awareness of how off-putting it was for customers other customers.It was genuinely disgusting, and I had to stop eating because of it and spare my food for take away.This kind of behavior from staff is unacceptable. I hope management takes this seriously and ensures the environment is clean, professional, and respectful for paying customers.
