The reason a clerk comments on what the customer is perusing is that he wants to engage the customer in a conversation. During that conversation, the customer might reveal the need she is trying to fulfil.

Nothing wrong with that.

And it's not high pressure.

I have not driven to the mall, found a parking space, made it through the thugs in the parking lot and into the store, to have a conversation with the sales clerk. If I am in a hurry I will ask for something, otherwise I will browse until I find it. “May I help you?” is enough conversation for me.
