question:
Good evening , madam . May I help you ?  I want a facial . But this is the first time I've come here , so can you tell me how you do it ?  Sure . Most facials start with a thorough cleaning . Then we usually use a toner to invigorate the skin , followed by exfoliation treatment-a peeling mask or scrub that removes the dead cells that make the skin lock dull . After that , we'll massage your face and neck with oil or cream to improve the circulation and relieve the tension , followed by a mask to moisturize and soften the skin .  That's exactly what I want . How long does it take ?  We have half-hour and one-hour treatments .  What's the regular price ?  Well , the half-hour facial costs 50 yuan and the one-hour costs 80 yuan . If you want make-up , another 20 yuan will do .  Good , I will take the one hour facial with make-up .  That's fine , madam .  By the way , could you give me a manicure ? Use a light nail-polish , please .  Yes , madam .

Yes
