You know, there's one thing you never want to hear from one of the suppliers a few days after you've done a two-hour session picking out plumbing, taps and sinks for the house: "I, uh, wasn't taking very good notes when we last met...". If your salesperson isn't taking notes as you're walking through the options, be a little blunt and ask if they're getting it all down. Because, trust me, trying to remember what tap "A" and tap "B" looked like a week after you saw them is very difficult. You don't want to make the wrong decisions, or worse, go back through another two-hour meeting...
