I Work In Retail

If you work in retail please be aware of service dog LAW in the us. You can ask.
1:is that a service dog?
2: what tasks does the dog provide?

However please ! Please! Please! Remove the fakes!!! If the dog is nipping, growling, barking, lunging, not walk-in on a leach as intended, sitting in a cart, being carried (unless hot pavement)
KICK THEM OUT
The ADA says that you can!
Also don’t ask for papers they don’t exist. If someone offers you some then are full of crap.
