Flirt but dun hurt.
Flirting makes people happy as long as you don't go overboard. Like
flirting with the sales person so that you get a good bargain is a
win-win situation.
There is a fine line between flirting and playing with people's
feeling. You need to understand this and decide if you want to do
so, because chances are the first few attempts, you'd probably hurt
but with practice, it becomes fun 
Just know your limits and the time to do so.
