I agree with @jond
during my college years I worked at a family owned hifi store, for our town some really excellent gear, Conrad Johnson, Phillips, Cary, Mission/Cyrus, Tannoy, Paradigm, Ariston, EV, NHT, NAD, Proton etc.. we had a small group that would come in in Saturday’s and make a visit. Always with some sort of doughnuts or pastry. We called the leaders of this band Siskel and Egghead. Fun guys, would buy some good stuff at times. (Like @larryi said the treats helped). Great conversations, introductions of new music and passing the time when sales were slow.
My boss taught me that this was part of the gig, our local clutch of audio heads. They all have friends that they push our way with potential sales etc.. If the gawking didn’t interfere with business, no harm no foul. (He also told me that I could chop off their fingers if anyone pulled a grill cover off)
