The check dodger. Every time you go out to eat, your friend offers to split the check. But when the check comes around, she claims sheâ€™s short on cash and sheâ€™ll pay you back the next time. Sheâ€™s just like Lynn from the TV show Girlfriends, who had more than her fair share of free lunches at her friendsâ€™ expense. The solution? Ask the waiter for separate checks. If thatâ€™s not possible, cancel your next lunch date. Maybe sheâ€™ll get the picture and pick up the tab next time--but donâ€™t hold your breath.
