Pick a number

My head of sales for China just asked me to select one or two girls from the following selection.

We are ‘selecting’ girls because apparently in China at a Trade Show you need ‘booth girls’. Or the chances of customers stopping by your booth is reduced somewhat.

Here is the exact email I got on the subject:

“Enclosed pls find out No.1~No.4 show girl photos for your review, the cost is 500RMB(~$100 AUD) per day. The girls are >165mm hight, ~20 years old, basic English speaking. You could pick 1 or 2 for our booth.

BTW, what do you want the girls wear? Office lady style(maybe with same orange color scarf), or more sexy style?
The vendor said they have 1500RMB show girl if we are not satisfied with those girls. Let me know if any concern. Thanks.”

Why do I feel a little uncomfortable being the one to make these choices?
