My first thought was "if it were me" I would never do that because first, I do not believe it would make a good impression on the customer for many reasons, and second, I believe it is very important to pay attention and concentrate on what I am doing. What's around me or behind me; furniture? A lamp? Etc..? Also, I can tell by "listening" to my machine (the vacuum noise; sound; etc...) what it is doing; what's happening.
Do you think I'm wrong on this?
