McDonalds has not the best reputation but this has been the worst fast food experience of my lifetime.
Besides waiting 20 minutes for a Big Mac, I witnessed a customer treatening to hit a member of staff. I am not sure what happened as I only arrived when the customer said he would "hit him later" and then left.
Then staff members began shouting at each other about using each other's cashier machines.
It was so obvious that the staff were untrained and completely unprofessional. The manager seemed to have lost control and was berating staff in front of other customers.
