I had a plumber come to my home and he did a repair. He did not arrive in a company vehicle, but a Jetta with no indication of a company name. After the repair when I asked what do I owe he said “we will bill you”. I was uncomfortable with that answer. I signed nothing to even indicate he was here. There was no paperwork whatsoever which I have never encountered. So I need to have an idea of what is reasonable in case there is a problem. He fixed a toilet leak and took approx 2 hours. Upon arrival he asked ME if I had a ladder and a flashlight, which I thought was weird. I have never before been asked if I had tools. I also had to run outside and turn the water off and on. I didn’t mind, but again, I have never had a repair person request tools and services from me. Thanks for any info.
