Are shower towels in your household one use then laundry pile, or do you use towels for multiple showers?

I used to reuse until my wife and I moved in together. Now they're one and done. We're visiting my mom, who made a remark about washing our towels after one use. Just curious about other households' towel policy.

ETA I showed my wife this post and she replied "In [dry place she's from] I'd reuse but not in [particularly moist place where we live] haha"
