24M working at a busy retail joint as a cashier and also some other retail stuff, I usually do make eye contact with customers but today I tried to avoid eye contact as much as possible and found I was able to handle the anxiety a bit better, especially at the cashier. Sometimes it's hard to avoid eye contact because I reflexively make eye contact when talking to people but I found it kinda effective. 

Is avoiding eye contact a good idea to help manage anxiety in a retail setting?
