The first salary

My London acquaintance had electricians working in the house - to turn the wiring, install the sockets, etc., all this took about one and a half months. The seven-year-old son of the acquaintance, Teo, he was constantly turning at the electricians under his feet, asking questions, touching instruments - the comrade thought to shout at him not to bother, but the electricians did not object and even kindly communicated with him.
A couple of weeks later, a friend received a letter from an electrician firm that contained a bill addressed to Teo and his salary of £15.
Decoding of the calculation list:
Measurement of different things - 1.50
Calculation and folding of the number of rosettes - 1.50
Catering (flavored cookies) – 1.50
Class Volunteering – 1.50
Quality control (a lot of questions) – 9.00
In total - 15 pounds sterling (a little more than 1500 rubles in equivalent).
Should I say that Teo is extremely proud of himself and his first salary?
