I was looking for a plumber to do a specific job, namely replace an existing saddle valve on a hot water line supplying a humidifier. I solicited quotes by e-mail and obtained a fair price with a fairly prompt response so "hired" this company. Given that I provided a full explanation of the job to be done (nothing complicated) and was provided with a quoted price, it was just a matter of getting the job done. On the day of the appointment, I received a call while I was on another call and the message was that they thought I had forgotten about the appointment so I should re-book. This made no sense so when I finished my other important call, I returned the message and was told that the plumber was on his way but I needed to send a photo immediately so he could determine what supplies were needed as he would have to purchase them. I thought this was rather odd to be asked to provide a photo at the last minute for a straightforward job.
