Am pm gas station Rude night manager Las Vegas Nevada

I went in the store to buy some items tonight, while I was paying for my purchase the man behinds the counter yells only debit or cash. So I used my debit card in which they charge to use. It asked if I wanted cash back, so while I was being charged to use my card I wanted to take money out. He started telling at me and cursing that I wanted cash back.  I was like " hold up man, I hav ethe right to get cash back and especially if ur going to charge me to use it" he continued on. I asked him to give me his name , he refused. I asked for the manager, he refused. He then said " just get the hell out if my store bi*ch"  i was take a back by this treatment. I went to the website to try to find a number for a manager or corp, there is no such number! Don't go to this store, as this man continued to tell at me bc I made work for him talk using my debit card in which scared me. This town is full if rude people but for such a national chain not to make their employeea wear a name tag, no number to call, or any type of coustmer support Is absurd! This man should be fired. But I have no one to even inform of this event! This is my corner store And I shouldnt be treated that why when I use that store almost every day. I would really like a number to a manager or corp to report this horrible treatment !
