Gatekeeper's #1 rule when running the lock... When locking PC (Pleasure Craft):
Once you start the lock gates/machinery, signal red light, never look back, stop the gates for anybody, no matter how much they whine and cry on the marine radio that their great grandmother is dying, second baby-mama is in labor, or the beer is getting warm and they need more ice.
Now... If it's @BringBackFergy or @Cripple Creek in a boat trying to pull some horseschit "priority" stunt... Then you close the lock even faster and go take a nice loooong break, preferably the one hour dump that's been brewing in your lower intestine since eating that football-sized "corn & black bean burrito suizo" you had for lunch! Those two need to "cool their jets" anyway and deserve the "quality time" thinking over and accessing the situation @ hand. ...Just saying!
