Expectations
This is another one that can bite you in the end of the transaction. understanding the expectations on both sides of the service provider as well as the client or guest are critical in completing a successful and well represented transaction. The difficult part is that both the exceptions on the customer's side as well as the service provider's side lie solely with the service provider. It is your job as the service provider to getting to what the customer expects as well as your job to lay out what can be expected. If this is not clearly communicated with the customer, this could result in very ugly outcomes. I have seen everything from dissatisfied customers storming out of an establishment because the expectations were not met to law suits being filed because service was not provided as expected and more so interpreted. There is no such thing as perfect communication and communication relies on at least two people which you only have control over one side as the service provider. However, you can take steps to ensuring that expectations have been clearly explained to the best of your ability and usually this results in some sort of release form requiring a signature or initials stating that the customer has an understanding of the expectations. Obviously the involvement depends on the type of services taking place, but the idea of communicating the expectations is the same.
