Sounds like that person needs a lesson in gratitude. I also learned how to clean on my own. Some people don't realize that it's time consuming, tiring, and doesn't always come out perfect. And the desire to keep up with the pace of your teammates also weighs heavy on a cleaner/re-drawers shoulders. Especially if you have a lot going on in life. Just remember, for every mean, miserable person that criticizes your work there are many, many people that are grateful and love you for your willingness to share something wonderful with them without compensation. Please don't be discouraged. I am grateful for all of your hard work and thank you.
