Actress Megan Fox always brings enough cash to provide waiters and waitresses a generous tip when she goes to restaurants and never tips less than $20.
The 27-year-old, who is currently pregnant with her second child with husband Brian Austin Green, always leaves big tips because she has worked in the service industry herself and knows how hard it can be.
''I always bring cash for tips, and I never give less than $20. I used to work in a smoothie shop, so I know the value of a tip," contactmusic.com quoted her as saying.
