Only if you take a Wednesday afternoon off work, not a lot of customers at that time of day, and make it clear you are just there to listen to some equipment, and ask if they have time to play some stuff (bring your own music)
Be appreciative and thankful, you will be amazed at how far an attitude like this will get you.
As a young lad of 11, me and my buds would go to the local audio shop, they knew we had no money, but what they did was show us gear, and play music for us, what they did know was that sometime in the future we would have money.
That sales rep played Santa Esmeralda though the the marble base Kenwood turntable with AR9 speakers. 40 yrs later I still remember it like yesterday.
I pity us as a society, I am convinced that within my lifetime the only stores left will be WalMart and Costco
