Seller : I'm selling xx at Ksh. 3,000. It is the best price I can give. It is non-negotiable. Potential customer : You are too expensive. I only have 1000. Seller : I can direct you to a shop that you can even get it at 500. If it is expensive here, you can try there. Potential customer : @%&#%@&@&***@. You are very arrogant. Your business won't prosper. Where do we draw the line between being honest and being arrogant? Or how are customers supposed to be talked to?
