Luckily I work from home so I advise all my clients well in advance when I will be closed and make sure they are all booked in before I go and after I get back.
I also post on my website, Facebook group, Facebook page and persona. I also have a separate work mobile with a voicemail message informing people I am away and when I will be back.
I also send a group text to all the people on my database to let them know.
I do miss out on customers, but such is life! My regulars are taken care of and that is the main thing.
Obviously having a shop is different and you will have to close - but I would prefer to do that than worry for a week about finding a therapist that I can trust completely - someone else looking after my customers properly, adhering to my standards is a big ask and I would rather lose some money than potentially lose all my customers!
I used to run a pub and had some hellish holidays with phone calls galore with problems, niggles and grievances from the staff.
My advice is plan in advance, close up for a week and relax!
Good luck xx
