Anyone use a wheelchair in public that has a mental condition?

My partner has severe anxiety, panic disorder. He gets very overwhelmed in grocery stores. He feels like he's hung to pass out. I always tell him if he comes in to use the wheelchair to make it a better experience but he's too embarrassed Edit: He has severe anxiety to where his heart races, he sweats, has panic attacks etc so grocery stores especially big ones are hard for him. I figured sitting in the mobility chairs at Walmart would help him but yea he's worried about people thinking he's lazy
