pshhhhhh.................. PLEASE, BS!!
I worked at several different places, it depends on the way you grew up~
One thing I noticed, however, is that teen buddies and young adults are idiots, they split their orders when I'm the drive through taking orders, I'm like, are you guys stupid? Why don't you just cover each other and make life easier for the both of us instead of trying to be greedy with every damn penny?
How many Caucasians offer you a glass of water when they let you into their house? How many African Americans promt you how your day was going? Will Asians say they're sorry? Do Hispanics try to tell you good things about yourself, or are they going to try to compete against you? Read this last paragraph one more time, and you will figure out that it doesn't matter because everyone grows up differently.
