When someone burns my bowl longer than a full second(if you can't get enough weed lit in a full 'one-one thousand', two tops, you're a fuck up.. or need a new lighter or a clean bowl). I don't really care how much/long the hit is. Some fucker burns it over 5 seconds and then asks me to load another, WTF. Or burning it when it's rolling. Or sitting & yapping with it while it's rolling, it goes out... then burning it.
Then again, if I didn't load the bowl I don't mind.
