>For me, if I go into Home Depot or somewhere it's more likely that the store was on my way home from work, I had a vague notion that "I need a new tape measure" or whatever, so I stop and go in. In that case, I have NO problem walking right back out if they make it hard to buy the thing I want. You stop in on your way from work. You see that tape measure, but it's locked down. There's an employee one aisle over who can help. You bail. The act of going to HD, parking, and going to find that tape measure probably takes about 5-10, maybe 15 mins depending on how far off of your route home the store is. Do you consider the cumulative time spent performing those tasks to have been wasted if you leave empty-handed?
