Tradesmen

Be fair in your negotiations.

You deserve to make a reasonable or even a high profit. Don't charge exorbitant prices.

Add a reasonable profit margin to the cost of your product or service. Don’t use fraudulent weights, measures, or qualities as pretext for jacking up your price.
 
Be honest with your suppliers and customers.

Assist the customer in choosing a product. Make sure the product purchased is the product needed and that it meets the qualities required.

Don’t purchase items from your suppliers that you are not sure you can pay for.

Don’t trade in dangerous, addictive substances.

Welcome customers politely and respectfully even if they don’t intend to purchase anything.

Selling defective goods constitutes fraud.
