Queue are always long with usually only one till open. Staff are not rude but they are not friendly and welcoming either. If you deal with customers you need to engage with people. It may just be a paycheck to the staff but you represent the company when you deal directy with customers.
Really handy as its close to where i live, would have been 5* but having homeless people sitting and begging outside isnt the best at all :/ very off putting at times
