Parking

In case you're planning a change of profession, and have finally zeroed in on becoming a parking attender or a security guard who's in charge of a parking lot, here's the one and only thing that they teach you during training, the only rule you will have to follow to the point of obsession if you plan to stay in the race and/or garner respect from your future peers despite being new in the profession:

When people have found parking space after hunting for nearly an hour, and have parked their bikes/cars and are about to go about their business, finally getting a chance to forget about parking-related woes, tell them that they shouldn't be parking there, and asked them to park elsewhere. Most importantly, before you tell them this, make sure that they have taken the trouble of side-locking bike, and if it's a car, ensure they have locked it, and the entire family has gotten out and has walked about 3-4 steps away from car.
