SPAR Virginia Freestate

For quite sometime now when I go to the SPAR here in Virginia in the Freestete there are ladies selling brooms and other stuff. Once I get out of my car they come to me and I politely say "no thank you" or I do not have any cash on me only my card" as for I do not carry any cash on me at all. When I come out of SPAR they will come again, then i will also tell them that I do not want to purchase the things they are selling. That one day they came to me four times, I mean how many times do I have to say "no thank you" for them to understand and leave. Can't the owner come out and ask them not to bother his clients, like the other businesses does? They are the reason we do not go to SPAR anymore, because you can not dare to climb out of your vehicle and not be harassed by them.
