America and its rules

I cannot get over how many rules there are in this country and if i was not surrounded by people in the know, i wonder how i would find out about it.....the hard way i guess.
What am i talking...i am taking about a few things. For example jay walking: i mean why would u be fined for walking when the light is red, everyone understands the risk of doing so and the fine is ridiculous in my opinion, i guess it is a cone from the state to make more cash, there is also the whole ID before you enter a bar: firstofall creating this 'forbidden' places to go probably raise the interest for the youngsters which otherwise would not care and think it is cool to hang out there cos' it is not forbidden, they wanna go. Then if they entered the bar they would not necessarily drink alcohool and even if they did one beer never killed anyone. I mean if i chose to go in a bar and not drink why would i need my ID? I guess then the bouncer would not have a 'raison d'etre' anymore....right?
But the worse of the rules i encountered yesterday was in Camarillo, by Lopa and Reid's house there is an outlet. So as you do in Amercica, you go and shop at the outlets, so off we go, i get into my first shop and decide to buy for 2 pairs of shoes (2 i know is a bit much but this is not the point i am making). When i get to the counter to pay and give my card away the lady tells me she needs my ID....why? I say WHY? She answers it is the store policy, i reply that i am actually spending money in her shop and she should just take the money and let me go with the shoes, then i have the impression i am actually talking to a robot.....IT IS THE STORE POLICY, ...i ask to talk to the store manager and there again i meet another robot: IT IS STORE POLICY....angry, annoyed, i leave the shop in a strop swearing......
30 min laters i go back to the car tell Matia about the story. He laughs and hands me over his card and ID and tells me to go and try to buy it. We laugh about it and even if i think it is a ridiculous suggestion, well i do it.....you need to have fun, right?
Anyway choose the same shoes (thank god for that) and go back to the counter where another girl takes my purchase. The previous lady looks at me, recognises me and apologises, the new girl looks at Matia's ID, look at me and take his credit card without a blink. Matia ends us paying for my shoes....bingo....can you believe it?
I guess i should just add for people who read this but have never seen my friend Matia, first he is a man, he is black and he has dreads....how does he look like me i don't know but i can tell you i am not sure i believe in America and its rules! Do you?
