Bad Microwave Controls

I can’t think of a consumer electronic/ appliance shop that lets you use the tv or microwave or whatever before buying. The sales experience is a feature list, or a sales person rattling off a feature list ( or not being able to, many a time my half an hour research into an appliance has given me more background than the sales person), or them telling me thats what they own, which depending on the person I take with a grain of salt. Most shops have a wall of TVs on but that’s about it. I bought a PVR a little while ago and wanted to view the remote before I purchased- they reacted if I asked them if I could take off my pants.
