Toddler is wild

My son turned 2 recently and I’ll try and take him out with me when I go shopping which isn’t very often but he will not listen, he tries to run away and won’t hold my hand and will throw the biggest tantrums so I basically end up carrying him out of the store and he’s screaming bloody murder. I see other parents with their

Kids and they walk beside them and listen to them and my son will not. I’ve tried being patient and not reacting too much to what he does but he will not listen and will run into people and try and leave places or run in the parking lot. Not sure what to do because now I either don’t take him out at all or keep him in his stroller
