A nice little old lady (about 40-45) came by my desk and asked about the gallon of water on it. Very polite this women was, we actually get along so it was easy for me to converse supporting my points with her. anyways, she asked about it and I said I usually drink 1-2 a day and she said "you buy one of those every single day?" When I told her I did and it was no big deal she said "yeah but thats everyday, that must cost you over a length of time" I said "well I notice that you either have a coffee from Tim Horton's (local like starbucks coffee chain) in the morning or a diet pepsi in the afternoon. This gallon is 89 cents at the store...while I bet your cofee and pepsi is at least double that" SHe thought long and hard at that one for a minute and said "well you can just fill that up in teh sink " I said "you can make your own coffee"
