Surely a manager at the checkout who yells at all her colleagues, it really can't be pleasant to work with her, especially if they're students, otherwise the service is 90% impeccable and cleanliness is always there.
The service is of no respect no hello not smiling he was a fairly bearded man and hair half short half long I advise you to go and talk to him, otherwise the food is very good the dishes are hot perfect 👌
