When does reading at Barnes and Nobles become morally wrong?

[TStoneMBD]

When I was about 17 there was a summer in which I would go to Barnes and Nobles just about every day, pick up a book and read it for like 3 hours. I never bought any books because I was reading them all there and enjoyed their setting. I wouldn't have read the books at home or anywhere else.

I felt bad about this and felt like I was mooching off the store so in exchange, every time I went to B&N I purchased a frap for like 4 bucks. I was tearing through like 4/5 books a month and didn't want to buy them after I'd finished reading them.

Some days I would go during the day when noone wanted to use the chairs and other days I would go at night and would have people waiting for a seat and would camp there for hours.

When do I cross the line of being a valued member of Barnes and Nobles and being a nuisance?

I feel like this thread is 1 star but this is a question that I thought about for quite a while.
