When getting something from a vending machine I prefer to get something with an 8 in the number.
My DMD (Diet Mountain Dew) fills a whole 2 rows in the pop machine.... I pick number 48 each time. I feel the 2 even numbers are luckiest - especially when an 8 is involved.
A snickers may sound really good and I might really want it, but if it's in the number 5 slot I'll pick the Twix in the number 8 slot instead.
