I was at longview location and I thought the teller was very rude, talking on her head set while I was trying to get waited on

I asked for service they showed me where I was already standing!!! Recieved only a tip I can bring back as much as I need!!!! Ok just need basic attachment for portable dishwasher. I Bought only option of extra length adapter. came back and asked if they could help they said to exchange!!! With what!!!!! Any idea option tell me they dont have something. So standing reading n no option even for standard attachment. Demand refund because they dont have anything??... or did they and I couldn't find? Asked if any other stores are open today they say no. 10 minutes later same town!!! Home depot open!!!! I am just wanting help I have all hardware on me. Oh yeah didnt need help at home depot found five options that all would have worked. I have a toddler he didnt like 3 trips for one part.
