I never had a problem with them at all. I've been going to that location for over a year. Either in the morning or late afternoon. Just chill and be patient with them. They're usually shorthanded in the mornings, with about 2 people on duty. That location is open 24 hours. The same person that served you was probably exhausted!
I don't know! Some people are just not nice. I never heard that problem there before though.
