There may be some confusion regarding caring for the CO and the resolution passed. Once a year there is a resolution passed by the congregation that send a suggested amount per publisher to the branch for the CO automobile insurance fund. That can be either a lump sum or broken down into 12 installments. of course the CO dosent a dime of that directly as it is billed as "car insurance" although i have no idea if thats where it actually goes or not once the branch gets it.
Then twice a year when the CO comes round he will often submit his "expenses" incured during his visit, including gas and misc food not provided by the congregation. Some congregations still pass a resolution to reimburse him for this as well although the BOE was sent a letter several years ago stating it wasnt nessary to pass a resolution on that each time he came to visit. That money does of course go directly to the CO, often in the form of a check. This is in addition to any gifts (green handshakes) he gets.
Hope this clarifies who gets what and for what :)
