seals under the lids of the
M&G mini bottles in SkyClub showers
I get why they exist, but at 0630 (after probably the least comfortable night I've ever spent in a D1 flat-bed seat) I completely forgot about them ... of course my hands were already wet when I realized why nothing was coming out of the body wash bottle, and I had to tear the damn thing off with my teeth ... and of course when repeating the process for the shampoo, the damn seal flap came off in my teeth and I had to use the cap nut on the shower seat to puncture the seal
