<human>: Provide a brief overview of the text.

I work in retail, and have many opportunities to talk to women.  Especially when I work the cash register, there is a few minutes to make casual conversation.  Often times women will come in, eye contact is made, chemistry seems to be there, conversation seems to be giving hints that they are single and interested.  It has felt inappropriate to make a move within such a short period of time after meeting someone, but most of the time I don't end up seeing the customer again, or for a very long time.   Should I just go for it, and maybe write down my number and say something like, "shoot me a text if you'd like to go out for coffee, if not that's cool" with a confidant smile?  Or should I wait for another chance to get to know them a little better?
<bot>: Is it appropriate to ask out a customer at a retail job, within the first few minutes of meeting them because you will probably not see them again?
