For those who can afford it, I would like to suggest that you add a few extra dollars when you tip workers that depend on tips and/or don't make a livable wage.
You could also offer to purchase something for them, like a meal so they can save that money on other necessities.
I was a restaurant server in 2008 when gas prices went up to $4/gal and I still remember the struggle. If you can afford to, a few more dollars out if you pocket will likely help them more than it would “hurt” you.
Please don't come for me in the comments I'm just trying to be a good person and help others.
