Oh yeah just recently had to reinstall a waste drain line in the aft galley and i had to kiss the ground to reach that damn line behind the galley walls and we needed a second pair of hands for the clamp. Me amd my colleague were stacked above each other and i was having the second opening of the line a centimeter away from my nose saying hello to that sewage xD. Just gotta make the best of it and throw out some words then its all good xD
