BradTips: Fountain Drinks

Next time you go to a Fine fast food establishment, where refills are free, don't fill your cup all the way. If you like me, there's always at least 2 sodas available that you want, but you force yourself to choose just one. If your eating in, just fill up your cup roughly half-way with one soda you wanted and sit down. Then before you leave, rinse out you cup with a little bit of water, & fill up your cup all the way with the other soda you wanted. and bwa-la! You just had 2 sodas for the price of one :)
