Funny black scheme (offline)

[Professor]

There are many options for implementing this scheme (you can implement it completely online)
The scheme is perfect for those who want to raise their SE and earn some good money

Preparation:

1. We select a city in which there are many houses with old entrances, intercoms, etc. We select these houses. (We do not work twice in the same city)
2. We buy universal keys for the intercom (google to help, if all rescuers have them, you can order them from any key manufacturer in your city)
3. We buy empty keys for intercoms on Ali. (We buy wholesale, the price was $0.1 per key, we ordered 10k at once for a couple of years in advance XD)
4. For all T-shirts we print caps, T-shirts Vizit, Tsifral. And it is better to find out the management company of the house and dress in their "symbols"
5. Don't forget about your own ass (Hair coloring, if black then burn it out, then go bald. Colored lenses, naturalness is desirable.)
6. A checklist in 3 columns: apartment - number of keys, signature. Above is the address and logo of "your" company, and we speak to each apartment

The gist: We go up to the top floor and start calling apartments: Hello, I represent the management company of your building. Next week we have a scheduled replacement of the door and intercom. In connection with this, we distribute the keys to this door in advance. The price of a set of 3 keys is $1, 1 additional key is $0.5. How many keys do you need?
They always take 1 set. In one building, we were able to convince the concierge to collect money for us (a concierge in a Soviet 9-story building is generally strange).
Now about the money,
one nine-story building with 4 entrances on the landing of which there are 4 apartments, 4 x 36 = 144 x $1 = $144, to go around such a house, my friend and I spent only an hour or 2.
We went around up to 9 houses a day.
P.S. never work in one city, and everything will be fine.
