paid to do a job, do the job. He's not being paid to take pictures and post them on a web site. Now I could be totally off base here and maybe he gave the guy a break on price or got his permission to do exactly this. If that's the case then kudos to him but if you're working on somebody's property then have some decorum and respect for that relationship. Think of it as if you've painted the inside of someone's house, you wouldn't just bring prospective clients inside the house without the owner's permission right? If the customer is happy with the work, the word will spread and let the work speak for itself.
I guess this post just really rubbed me the wrong way or perhaps my sugar level is just going low. :)
