i once did, it was really embarrassing and looked so ghetto, i was just having some coffee with a girl in college and on the way back i stopped to pick up a 40 for me and a friend, the girl was still with me, but she ended up being annoying so i didnt really care what she thought
so here i am buying 2 40's and paying with my CC, and it kept get denied...everyone was looking at me...and i started making the face like everyone does, claiming they dont know whats going on, but i actually didnt...then when i got home i got to the mail and there was a new card, as mine had expired a day or two before.
