Afraid to shop at Checkers in Upington

I am afraid of birds and both our Checkers shops in Upington have birds flying around in the shops. I had spoken to management about it, but I think they think that this isn't a serious issue. They said that the birds fly into the shops and that they can't do anything about it. I really can't shop with birds landing close to me when I do my grocery shopping. It doesb't feel clean and I am so afraid of these birds that I can't concentrate on what I need to buy.
