@Colleen253 It's not just guests- people in general these days seem to have the attention span of a goldfish. If they have to read something longer than a one line text message, they just zone out. And heaven forbid they actually go back to see if the information they want has already been addressed.
I just had an upholstery client like that. First she asked for an estimate- I sent her a detailed email listing all the materials I'd need to purchase and my labor cost. Then she wanted to change some of what she wanted, so I had to redo the estimate. I told her I'd need the money for the fabric I had to order first, then when I was ready to go purchase the rest of the materials, I'd get the rest of the materials $. So she gave me the $ for the fabric order, then when I asked her for the rest that I needed, she wrote "I don't understand- I already gave you $xx." I said that was for the fabric, as I had previously told her. Then she asked if the rest I needed was part of the original estimate, or in addition. All she had to do was look at the original estimate to see that. She also decided after I did the second estimate that she wanted a couple of single bed size pieces of foam to beef up the thinnish mattresses. I said that would cost an additional $xx, not included on the estimate. She said that was fine, then when I added that to the money she owed me, she asked what the additional foam charge was for. It continued on like that. She drove me crazy.
