My daughter works at Mark and Sparks and tbh I couldn't do it. Fortunately she's a friendly girl and she manages to cope with the rubbish but personally I couldn't do it for what they pay.
One idiot mistook her friendly nature for something else and actually knocked on our door one day with a bag of reduced groceries as a gift for her. She was in on her own and getting ready for work and absolutely freaked out as he was about 25 years older than her.
We laugh at most of her stories but there's some strange people out there.
