I saw a traveling provider recently and experienced the same thing. Minutes after the session started I noticed that he was only using one hand and not very attentively. Clearly he was texting with the other hand. I gave him the benefit of the doubt thinking it would be brief...it wasn’t. After about 5 minutes of this I did look up and it was confirmed. I told him that if he wasn’t into the massage I would leave...and I started to get up to go. To his credit, he was extremely apologetic, said he was putting it down for good, and offered to discount the session by $50. Reluctantly I stayed, but I’m glad I did. The rest of the session was good and he did not use his phone again.
Gotta speak up sometimes. Although not sure all providers would have responded as gracefully as he did.
