I did a dining shop for them in Tennessee. One of the companies I branched out to. The credit card receipt was not itemized and I thought of returning that night and asking for one, but when I filled out their report, they had that part set up for credit card receipts.
Further, I received emails about my bar tab. I had rolled it into the dining bill. I tried to explain, but they insisted in adding another $2.73 to my reimbursement, and who was I to argue. I did get another email towards the time of reimbursement and I explained the beer was included in the total tab, so I didn't get the extra.
Do not read so much, look about you and think of what you see there.
