Love people's shitty attitudes towards traffic cops. If you get pulled fo whatever reason, teh only words to leave you mouth should be...
"hello office"
"I'm sorry officer"
"thank you officer"
"never again officer"
"have a nice evening officer"
*shake their hand*
I've been pulled a few times, and as long as you have a smile on your face, you don't dress/look/act like an oxygen stealer, then you will be fine. Police are fairly leanient sometimes, and as long as you don't try and make escuses, or give them jip, they won't have an attitude with you.
I HAVE had cops with a bad attitude pull me before, and be very unreasonable. But keep calm, and cooperate, and they can't start an argument with you.
Police are there for the greater good, I'd prefer to be pulled and know they are doing their job rather than sat in a lay-by reading nuts.
