[quote name='Pete Academy' post='542568' date='Jul 16 2009, 08:15 PM']I will help any customer out and give them good advice, but when you have someone who just wants to kill half an hour trying out an all-black bass, slapping the hell out of and scratching it to f##k, you have to draw the line.[/quote]
I was doing a case in Scunthorpe a few weeks ago (purely to see what the place is actually like) and I found an old-fashioned music shop next to the court. I came clean at the beginning and said I had half an hour to kill before I was due in court, explained that I'd like to buy two or three smaller items, and basically asked if I could noodle on one of their guitars as well for a while - that I probably wouldn't realistically be buying.
They were totally cool with that, very nice, very friendly, very professional and very accommodating.
Even if you're just killing time, there's no reason why you shouldn't be upfront about it.
