Worth paying for a certificate? (update)

I am considering a short certificate to improve my chances as a hotel front-desk agent. I would rather hear the honest version than the polite one. I would like to use funding if possible. Did a certificate help you get hired?

The workforce centre told me about training funds I qualified for. It covered most of my course.

Check a dozen job postings first. If most ask for the same certificate, it is probably worth it.
