@Robert Gentel,
You're absolutely right!
We can really eliminate a lot of doors that are already in existance too.
At the HEB I usually go to, you really don't need a door. You have to walk in and around the corner anyway.
If you could get in and out, and not have to use hand dryers where you have to be careful not to touch the sides, like those Dyson Airblades, I'd be all for just having air dryers.
I really don't know what Dyson was thinking with those air blades. I've had 2 other people mention the same thing, one of them a male friend.
We went to a Shake Shack awhile ago, and he came out saying "They have a Dyson in there, but a different kind where you don't have to run your hands in and out."
Are you in Texas or Mexico right now?
