Fixing bent rear derailleur with big screwdriver

Well, I always used my bare hands. When the derailleur (actually the hanger) is merely bent inward, aligning it by eye does take some skill but is not extremely difficult. In cases where the bike has merely fallen over or similar it's often the case that the bend is simply inward. But there are other times where the hanger is twisted as well. In that case it is more difficult to get alignment correct without a gauge, as it's harder to judge parallel. I have always been very good at aligning frames and components by eye, but when my rear derailleur hanger was tweaked in an accident I could not get it right again until I used a gauge.
So I am of two opinions on the OP's experience. The mechanic's fix worked, and that's great. There's nothing wrong with trying a quick fix if it works. But in this day and age I would flat out not trust a shop that does not have a dropout alignment gauge and claims to not need one.
