I think a very common tip increasing strategy used by people serving food is to give discounts. If I'm selling you something for $10 and you'd normally tip $1 and I give it to you for $8, you are much more inclined to tip me $2-3, because you'd still pay the same or less and received "special" service.
This of course may be unethical for the employee, depending on store policy. My best friend falls for it every time, tipping back up to "full" price. I see it as a type of scam against the employer, though.
