BennyJets said "Is normal to me. I have a friend that does the same. I call it maximizing my time. I’ve never wasted the c&c delivery people’s time. I park, run in quick and then wait in my car. It’s not as though I run in and get a full basket of items, I’m running in to get one thing. It affects no one but me. "
Just because your friend does it doesn't make it right. What if everyone did this? All the spots would be full, with all the cars empty. You would all be lined up at the pharmacy and some of you would miss your orders being brought out. Actually that would be amusing in a way.
I guess by your standards anyone can park in those spots-run in, grab one item, get back out quick and leave, it affects no one but that person, right?
When I leave reviews on my shopping experience, I always mention the empty cars parked in the pick up spots. Maybe some day the stores will. Figure out how to fix the issue: the clerks have expressed their disgust with those shoppers too.
