Proofreading

Why would a business NOT utilize a proofreader for their signs and displays. In the last week, I've seen the following:

Furrciletie (instead of facility) on a sign at a local mall.

Japonncheese/Japonayze instead of Japanese on the menu of a steak place.

Raizonne beggel at a deli.

Why why WHY?? In this day and age, it would have been so easy to have had these words spelled correctly. It boggles my mind!
