I've seen far worse-- I have a client that does far worse-- but the Delta surveys are poorly designed and annoying when you get one for *every* flight.
I'm putting the below, or something like it, in the last field of each survey, and otherwise ignoring:
I have five of these surveys from the past week. They are poorly designed. The circles are very small and hard to click on. Make the buttons BIG and make them check onHover and I'll fill them out again, otherwise they take too much time to fill out.
I hope someone over there knows what "check onHover" means.
