 But something like a spa procedure where you need to have the surgery set up, you need to have the anesthetic, you need to have the consumables and then at least one nurse to monitor it, and you need to have the vet who's trained in doing the procedure, some scent home medications and all of that is very variable and it's very hard to work out the cost of that and so clients go home with a bill that's got 20 or 30 lines on it because that's the only way to actually fairly pass on all of those fees is to work out what each of the things costs individually. We try to make it really obvious that you've spent money on the theatre, you've spent money on the anesthetic nurse and you've spent money on the vet doing the actual surgery and that's how it comes up to the end. We don't dollars and cents people so we don't make it down to the, we spent 30 cents on a shot of penicillin here but we do make sure it's really obvious they know exactly what we've done and that's one of the things that that vets compete on is their prices for desexing so you will see some people offer cheaper desexings but often they're doing different things they're not recovering them with a nurse or they're not necessarily using as much pain relief all of those sorts of things.
