I had a guy for a 2 hour booking whose phone kept pinging as I was riding him, he kept picking it up, smiling, responding and putting it down as if I wasn't even there. Pretty sure it was a mate rather than a girlfriend or wife but still, waste your money if you want pal, I just carried on and ignored it, his money he's wasting!
Answering the phone to a girlfriend or wife as he is with you though, disgusting and ignorant. And stupid, I mean what if you were to cough by mistake? Ooops!
