A familiar American made repairs in the apartment, and put the switch in the bathroom in the American way: inside the bathroom. Type so it will save on the fact that the light does not burn while he enters the bathroom or goes out.
I congratulated him and calculated: the one-time saving of the entry-out would be 2 seconds. 1 minute a day, 6 hours a year. At the power of the lamps 18x5 = 90 W and tariff 5. 38 year savings will be 2 rubles 90 kopecks.
Payment for transfer of the switch - 800 rubles.
I’ve never seen him so ugly...
