Kendall Jenner -- I Eat, I Pay, I Tip

Kendall Jenner wants to prove she's no food bill scofflaw ... which is why she not only paid for an expensive meal Tuesday -- she also left the server a big fat tip.

Kendall hit up Pearl's liquor bar in West Hollywood with Stephen Baldwin and his daughter Hailey. We're told the tab came to $554 ... and Kendall covered the whole thing ... AND left a $160 tip.
