Whether it's Amazon or not is irrelevant. In any large company, there's going to be a percentage who like the dead tree copies of the book. Got to a restaurant when the staff are on a break, you'll find some folks eating Mackers/KFC/their own sandwiches.
This. The greater the population, the more people will wander into your store - even if it is just to get out of the rain. Sudden showers also drive traffic to your store. Is rainfall your new ally?
OTOH, I find it silly that people talk about Amazon being the enemy of your company. The true enemy of your organization was that you were relying on physical constraints to force customers to your store due to a lack of choice - especially now that Amazon is charging tax in many states. If you provide a service to your customers that Amazon cannot duplicate (being non-physical) then there will be a sizeable segment of the population that will flock to you. I visit my public library and stores because they offer a benefit that Starbucks and BitTorrent do not - a special of the day, an illusion (and sometimes real) friendliness, and an update on local events that I don't get from a vending machine. If you claim Starbucks is driving you out of business, you would have gone out of business by a bunch of vending machines.
Yes, amazon can run at a loss much longer than my local bookstore owner can - which is why she is friendly, holds book reading events, and takes an effort to ensure her customers leave the store happy. She doesn't compete with Amazon on price - she does it on service. When my Kindle DX malfunctioned long after the warranty expired, Amazon customer service replaced it without hesitation. Best Buy would charge me a restocking fee if I changed my mind five seconds after I paid.
