As an employee of a contractor, and one who works on contract work, I can tell you there are a few iron clad rules that are in common between all trades, for everyone's benefit: 1. Get it in writing. 2. Get it in writing. 3. Get it in writing. The best way to assure that you never have to worry about this is to produce detailed specifications before the project commences. I know this can be boring, but believe me, the biggest conflicts we have had with customers were when they didn't have an architect and a detailed spec, and we 'misinterpreted' their hand-wave and couldn't read their mind properly. Best would be to find that three-page form that globetrotter has and copy it, and fill it out thoroughly for every project. Include drawings, photos, etc. More detail from the outset will exponentially decrease the chances of your being unhappy with the finished product, and in the case of a dispute, it is easily resolved. As for disputes, we tell our customers that if they are unhappy with the product, they should tell us, and if they are happy, they should tell their friends. Obviously an honorable person will give the contractor (tailor) a chance to fix the problem, or agree on a concession (lower price) to live with the problem. In the latter case, however, it is my experience that they are never as happy, as should be obvious. In the case of a suit, you can always refuse delivery of the product, and if you don't have good references for the tailor's reputation, you should buy it on a credit card so that you will have more power in dispute resolution.
