我以前的老爷车被拖了好几次的，我们都没哟给。
曾经尝试过给他，居然人家不肯收，8知道是不是嫌太少了，

It's better for u to tip those who provide serivces... It is about respect not money...

there is no problem to tip the driver, but it's totally different thing when the drive threats him to get the tip!

Threat is too strong le...
I know lots of chinese don't tip at all, that is probably why the driver asks for tip. To change their opinions, please do remember to tip...

我曾经叫过一次AAA来拖车（唯一的一次， 虽然每年都买 AAA membership）， 大概有不到3 miles远吧， 到了目的地后， 我给他一张$5的作小费， 他居然不收。 我现在也想知道， 到底是AAA的driver都不用给小费， 还是他嫌少了， 如果是后者的话， 到底这样的拖车应该付多少小费才是acceptable呢？

$5 应该不算太少, 如果给他,他不收就无所谓了.. 一般一次拖车是三四十块, 所以应该不是嫌少.

i normally give at a price of $5.00 for tow or open car door, but in case if i dont have cash on me, which happens alot. (i would try to provide else thing instead.)

真的啊？我用过一次车行的开锁（新车带的24小时紧急救助），当时没有想到有给小费，真是不知道耶~~不好意思
