tip on tax?
Perhaps I missed other remarks, but I saw only one comment that mentioned the amount on which one might tip a percentage. In particular, if one believes in tipping a percentage, should it be on the menu price or the total check? I have some trouble seeing why the tip should go up because the local jurisdiction has imposed a restaurant tax, but I could be missing something.
On a slightly related theme, should one tip on a free meal? One example would be an Embassy Suites, where everyone gets a free breakfast. Tip the busboy? Another case would be a Hyatt Regency, where a diamond HGP member gets a complimentary breakfast. Tip?
Thanks for your thoughts.
