It's tacky because it's bringing too much attention to the assumed tip scale. Customers should not need to be solicited like that by putting words like GREAT! and WOW! And then also put nothing next to the 16%. It's just tacky. And it shouldn't have the tip scale ABOVE where you enter the tip and sign the bill. It should be at the bottom, out of the way. This tactic FORCES them to read through the tip scale before they even get to the part where they enter the tip and total. FURTHERMORE, it says "Please circle your gratuity choice or write in a different amount below." It's heavily implying that they almost have to pick one of the numbers before they even sign the bill. It's dirty. I don't like it.
Having all that on the check is just lame, and putting it ABOVE the tip/total section is super tacky and pushy. Let the customers decide what they want to tip. Put the tip scale at the bottom of the check for those that wanna use it, but don't just interject it right in the middle of the god damn check with words like GREAT! and WOW!! next to the higher numbers. I've never worked in a restaurant that would do that, and I bet this has got to be some sort of struggle diner or something else like that where they are too ignorant to realize how tacky that is.
