Last Sunday.I was restaurant with my boyfriend and a waiter

Last Sunday.I was restaurant with my boyfriend and a waiter here was really nice.He set chair for us，brought their menu and kind suggested the special offer that day.I was surprised when my boyfriend said，“He seems interested you Keep smiling at him or we might get some food for free”I kept smiling，showing his eight teeth，at the waiter at every time I caught his eyes.But it was only when I eventually went to the toilet that I notice I had a vegetable leaf in my front teeth.
