When I worked at national-chain grocer here in Georgia, we were once given this awful (and somewhat sexist, IMHO) list of questions that we were supposed to use with our customers.
Some of the suggestions were okay, and well within the realm of what I would consider "normal" convo for a cashier and customer - things like asking about a particular item a customer is buying, letting the customer know if a similar item is on sale for less, the weather.
But then the list went into a list specifically "for women," which included things like asking about a female shopper got her hair done, complimenting on how much we like her clothes/jewelry, etc. We were also instructed to "discuss recipes" (fair enough, but only with female customers?!!) and so on.
As far as I could tell, most, if not all, of my co-workers were smart enough to ignore those instructions.
