Hey, just ignore them! If they were so smart they should have figured it out sooner!
My late husband could fix anything at the side of the road and was one clever & well respected bloke but he held the record for running out of fuel in most county's in the UK and most of the countries in europe! I couldn't begin to tell you the amount of times we rambled up & down the side of the road looking for a discarded can to use to decant fuel from my bike or someone else's into his! ;D
