I do not want businesses to adopt this Apple store business practice. I hate having to hunt someone down to ring me up. I hate seeing three employees with nothing to do, and none of them can check me out.
... Did it ever occur to you to walk up to said store employees and tell them you wanted to check out? In my experience, retail employees tend to gather after walking over the whole floor and asking if someone needs help, only to be gruffly rebuked as if they were offering a rusty knife to your baby. Thus, they pretty much just want to let people shop and wait until they're finished. If they aren't bugging you, chances are they just haven't seen you or can't tell if you're finished or not and don't want to get their heads bit off during the process of finding out.
Sorry if that comes off as a bit of a rant, but after working retail for the past few years of my life, the amount of bitching and moaning some customers make over their own lack of communication/communication skills never ceases to amaze and frustrate me.
