If a person occupies a salesperson and leaves without making a purchase, what is the commission? No sale seems to come to 0 unless you have some other form of logic you'd care to share with me, I was speaking in scaling terms not absolute but the analogy can work for the absolute as well. A customer can keep a salesperson occupied for some time and be just as much a dick and not pay for anything as someone who sits down eats and doesn't tip. A salesperson can be shit, just as a server can be, and as result make fewer sales hence lower commission, or as pointed out they can be great at their job and by that alone increase their sales and commission just as a server can provide better service and increase their earnings. What is the strongest link between this analogy: customer service, uncapped earnings, and fluctuating income. As for the reason for the comparison both fall under Pay-for-performance systems, and the point being repeatedly brought up is the servers "make less than minimum wage" so do many commission workers.What the fuck? You aren't talking about buying 3 pair you are talking about determining whether the salesperson deserves a undervalued(or even 0) commission. How are you this bad at constructing analogies?
