Worst service ever

I was at the liquor place at Game in pincrest and I bought bubble gum, as per customer service the lady should have asked what type of stiromol are you requesting she choose which ever which is ok as I didn't indicate, so I wanted to change the gum there is alone lady she was busy with paper work, I thought if a customer comes and you busy with paper work you stop and help customer but that's not how game works, after she then helps a colleague who came after me, you know what you can keep the gum i will never shop there again ever
