Depends on the vernacular used with the customers in front of you, I would imagine. If she speaks actual english instead of the pidgin that is ebonics, if that's why you go shopping then go for it. If you hear "acks" at any point, I would say it is probably worth changing lines. You never know what shenanigans could occur in that type of environment. Dogs and cats... living together.
There's a reasonable amount of cancellation going on, but there's also some clear warning signs.
