Yes. I did maintenance at apartments for college students (which is probably a factor), and plunging their toilets was a regular occurrence. We kept a plunger on the golf cart for this reason, they often didn't own one.

One side note since you mentioned Drano: it made things more difficult for me because they'd use it on more than just clogged toilets: clogged sinks and bathtub drains, which are caused by hair. Using Drano when it's already backed up just dilutes the Drano, rendering it next to useless. I'd have to go fetch gloves and then rigorously clean the acid off my needlenose pliers after removing the hairball.
