Small Profits

I figured there is an easy way for generating income people have. I was paying a water bill the other day and found out that the employer can make good profits on a monthly basis. And the reason is that no one anymore deals with anything less than five Syrian Pounds, as a rule. So this employer will have bills like 223 SP, 367 SP, and 146 Sp and he would bill them as 225, 370, and 150 respectively. So every bill is rounded to the next factor of 5. At the end of the day he will have to report an amount that matches the sum of the bills paid, and he gets the rest.
So to do a bit of calculation, if he works 9 hours a day 5 days a week: that is roughly 180 hours a month. If we assume an average of 3 SP extra per bill, and serving 20 people per hour: that is 60 SP per hour. If we multiply by 180 that is 10800 SP per month. Of course the poor officer probably deserves more than that, and the number I cam up with may be smaller than the real one.
Same thing applies to beggars. If they bother 50-60 people per hour and they get 4 to give them 5-10 SP, and average of 7.5 SP that means 30 SP per hour. This is multiplied by 300 hours per month (as beggar don't have a union or a weekend they can work 10 hours a day for 30 days a month) and the sum is 9000 SP per month. That is better than a lot of salaries in the government. I am not sure whether I am exaggerating but because of this I refuse to pay beggars and wish they find a decent work to do and at least earn the money.
