On my visit to purchase a $6-8k spa, I was ignored completely by everyone I walked up to. After several laps around the spa area, and about 10 minutes of this BS, I went back to the front of the store, to the customer service counter, to ask for help. I stood there another few minutes while 4 sales clerks discussed a clearly more important customer than I (who all told spent about an hour with several sales people, was clearly price shopping, and ended up not buying ANYTHING).
I finally got some "service" once they realized I actually wanted to give them thousands of dollars. Hilariously, the sales guy kept touting their fantastic service, which based on how I just had been completely ignored, I don't exactly believe.
They also sell tons of patio furniture and some awful yard "decor" (who buys this crap??)
Bottom line: look like you have tons o' money (read: older and rude, demanding personality) and you'll get service, regardless of whether you have intentions of actually buying anything.
