How Do You Use Testers?

Every beauty boutique worth its salt has product testers that you can dip into. Some people touch the containers of lip gloss and blush with their fingers, others use Q-tips to apply products to their faces, and others refuse to touch them at all. Even though I've never heard of anyone getting sick from a less-than-hygienic tester, I use Q-tips to apply samples only on the backs of my hand. Which way do you use testers? (Your secret's safe with me, I promise.)
