In a small town, I'd imagine that Mom and Pop would prefer to use their own name like JetsPizza or Tonyspizza. It would be on all their coupons and flyers anyway so it won't be like you are sitting there going hmmm, wonder who I should call? If they put up a billboard, then travelers would know as well. Also, hotels that have local adverstisments for travelers would probably have the Go800 number in the pizza ad.
By the way, I crack the Fxxk up every time I see HairNutz posting because the name is freakin halarious! So HairNutz, how did you ever come up with that handle? LMFAO!
