You know what? YOU are the sort of buyer who should not be allowed to walk into a store. Why do you walk in there? You know enough about the goods any way. Ah but you like to look at the merchandise, see it hear it touch it feel its operation. Why don't you just go online, sight unseen and buy it? Or go to the el cheapo wharehouse and get it there? Oh but you wanna see it working, you wanna try it out,or because you like the convenience and comfort of the shop. YOU might know this but YOU have just USED a SERVICE, taken up someones time who needs to earn a living from providing that service. It costs them MONEY to provide you with that shop front service. Next time you go to work to your job go in there without taking any pay for your time say half an hour each day for the next year, and explain to your family why you didn't get paid as much this year
