I always do whichever I do first, then do the other one. And I never forget to close the caps, except for that one time last week ...
We have all been there! My most recent duh moment was forgetting to put in the oil cap when I met up with the tree crew. Grabbed the saw and oil bathed the front of my jeans...... good times right
One time im cleaning roofing cement asphalt off a stovepipe flashing with "Goof Off" which i believe is xylene. It was too thick, so i used my little torch to soften and scrape it off. Not paying full attention as im using the torch i catch the rag on fire. Dropped and stomped on it to extinguish the two foot flame. A few seconds later i feel heat on my leg. Ended up catching my pant leg on fire when i stomped it out!
