Without explicityly disageeing with the YES answers,
sort of conditional Yes. BUT ...
As in any 'art' how you charge is up to you.
You may decide that your charged rate for the main work includes a percentage for unavoidable related activities.
Ultimately you need to set a rate which you are happy with the results of and which people will pay - and hopefully will be happy to pay.
A potential risk of itemising 'extras' is that SOME people MAY see it as gilding the lily / trying to add on some extra unseen costs / ... .
And if people did not want to pay would you be happy to accept less overall? My 'art' is photography - and/but when I charge it's for a all up package. If I photograph a wedding you'll get a practice session, bride's house, groom too if doable, church, garden etc, reception till end. If they want "just 4 hours" there are people who will oblige.
I'm not suggesting that you charge 'less' or do "free stuff' - just that the extras are an explicit part of the main job.
Note that the above is NOT THE right answer - it's just A right answer. Whether it's the right answer for you is up to you.
