Once, from a local Italian restaurant. I tried to be "good" and transfer the food from containers into plates, etc., but I was so clumsy about it ( not something that I usually do) that it probably didn't make a difference anyway. Probably not gonna bother with it next time. I feel the risk is low enough to make it not worth it. Just wash hands before and after, which is what I'd do anyway.
Also went through the drive thru at McDonalds once, parked and ate in the car. Just used hand sanitizer for that, which is something I always do.
