You own a pet grooming shop and you will receive payments using bitcoin and altcoin. Do you mean so?
I think it's good if you want to accept payments using crypto currency, everyone buys to your pet shop, but you should first introduce to your local community about bitcoin and other altcoins.
If this is a big city then there will be enough advertising. I am sure that the news about the store that accepts Bitcoin and altcoins will spread quickly among people
