Hi guys, although I do agree with @Branka-and-Silvia0 I would not pursue compensation through the resolution centre! Your chances of success are fairly minimal and if the guest feels you are going to make some claim on him he will leave you a really bad review and that may have a long term consequences for you.
There are many great cleaning agents on the market now which restore just about anything to its former glory. We have to cope with Make-up, blood, red wine, beetroot and other food dyes.....it just comes with the territory. But we have the appropriate cleaning agents to put it right again!
If the guest is still there say to him that the stain is disappointing, unfortunate and not something that you welcome but with a bit of hard work on your part it should be ok. That puts the guest to shame but, as you have not penalised him, would also feel he needs to review you kindly.
Your call guys but these minor things really need to be dealt with in house rather than making a big deal that will end poorly for you!
Cheers.....Rob
