Yeah, I've got a few with the vented straight spouts that are just aggravating, especially when you're standing there trying to fill the tractor and have to hold them head high, upside down, with the little ear hooked over the rim of the fuel tank so it opens the vent.
Then I have a couple that you have to pull the button back, and mash the lever down, and the spout on them is maybe 3 inches long. Came home from ND in a Ford pickup, with a 16 gallon tank, and didn't have gas stops figured out on that small tank for a Sunday afternoon across the Midwest, where they roll the sidewalks in for the weekends in small towns. Was all Wally World had at the time, and they were the only place open at the ridiculous hour I headed out. Actually had to use them, and the neck on the can wasn't long enough to get all the gas in my truck. Barely reached the fill neck. Dumped about half of one can in, dumped half the other can in, then dumped the remaining half of one can into the other, and dumped that in. PITA!! And, yes I smelled like gas for about 250 miles.
