Is it wrong to flirt with service staff to get free food?

Not saying it works 100 percent of the time. But if my waitress is cute sometimes I go in dressed up. Like a cowboy shirt and I just talk to her and see how she reacts. If she isn’t giving in seems face nice or like she got a man I drop it.

But I get like free deserts and constant refills. Just all kinds of stuff. Had my dinner on the house once at Texas Roadhouse cause I kept flirting with this girl there. I left a tip about the size of what the meal costed so. Don’t worry about that.
