1Stop10 review: Servicing the customer

I went to this store.
I chose 4 $1.61 sodas and sat them on the counter.
Come to find out she doesn't have the tickets I want.
I went to a store nearby to get the tickets and soda.
They had the tickets but not the sodas I want.
I purchased the tickets and went back here to get the sodas.
She says shes not selling this item to me because I left them on the counter before I left.
I actually did put them away.
She kicks me out of the store for arguing with her.
I told her I need a business card or phone number to contact her superior.
Another no.
