I agree completely. They should be banned. I actually had a guy in a truck with a trailer almost crash into the side of my pickup in a gas station at 5 mph. He was busy trying to talk while pulling out and obviously could not walk and chew gum at the same time.
I think they should be banned in grocery stores having been run into by a woman’s cart who was busy describing to someone the cereal she was buying.
I saw a guy standing in the aisle describing to his wife just about everything on the shelf because the nincompoop couldn’t figure out what to buy or was so hen-pecked he couldn’t make a grocery decision without consulting her. If you take his cell phone he’d probably be reduced to a drooling quivering lump of goo.
