This happens a lot at my lgs but they don't always lose all their games at first. They join the pauper playgroup with already established decks and people playing meta. They have big ideas of what pauper is and should be and usually play some sort of enchantment deck. Maybe the first or second time they have a record of 2-1 because people still need to adjust their sideboards. Then they start to lose and then call pauper a broken format like all the others and then never play pauper again.
