Competition is fierce for many fast food restaurants. Most of the time, menus are very similar so much so that businesses have to get creative to get people to eat at their locations. Drive-thru’s commonly use signs to lure in hungry customers. A little humour and combo meal messages usually do the trick. Nonetheless, what is supposed to be a painless and easy task to attract more business, can turn into a rather embarrassing situation. As for potential customers, some may just be too hungry to read. Here are some of the funniest fast food signs. So glad to know #4.
