Dollar Tree

On Friday December 20, 2019 I went into Dollar tree to shop. Was looking for some Ajax clothes detergent but there was only one bottle, so I finished getting what I cam in there for headed to the register to ask the cashier if there were any more. She thens call Mr.Winston whom is the manager to ask him if there is more in the store, he goes looking around the store and found one more bottle he says " this is all we have I said ok I will take it thank you. He then stares and speaks to me and I ignored him he spoke again and I said " I don't speak to you we are not friends "! He then jus looked at watched me leave the store comes out like maybe 2 minutes later with what is my problem stay out of my store, you have no need to come in my store! I ignored him got in my vehicle and left! Then I get a call at 1:30 am with him harassing me yelling and telling me this is his store and I better not come back in his store again! Something needs to be said to him about his behavior! I do not feel safe in the store anymore because of him and I shouldn't have to travel to another store because of one person!
