Los Angeles: Actress Megan Fox says she always carries enough cash to give a generous tip in the restaurant and makes sure it is never less than USD 20.
The 27-year-old `Transformers` star, who is currently expecting her second child with husband Brian Austin Green, always leaves big tips in the restaurant as she understands its value, reported Us magazine.
"I always bring cash for tips, and I never give less than USD 20. I used to work in a smoothie shop, so I know the value of a tip," Fox said.
The actress said she carries a particular pen, black Sharpies in her bag as it gives a clean handwriting.
