That happened to one of the guys on my fire dept on scene at a fully involved structure fire high 90's out. He goes over to the house can i please use your bathroom-bam. When im out on route i always make a note of office complexes doctors offices etc. I always go there there are usually bathrooms in the hallways that are kept clean. Gas stations i like to pass on Id sit my arss on a log in the woods than a gas station b-room. Reminds me of the time we were installing an irrigation system out in the middle of nowhere heavy heavy heavy mosquitos place was surrounded by swamp- bam get the gut bomb, i go into the swamp with a can of deep woods off and had to spray i around back to keep the skeeters away. sorry for the visual, anyway im holding onto a tree and spraying away, shortly there after my arse and my sac were on fire I had to go home and shower to stop it from burning, i think mace in the face would have been more pleasant.
