Breaking a bowl, coffee mug or plate can happen. And we're used to it. It can happen. 😁 There's no charge for that and no need to replace it. No worries.
Also, in lots of cultures around the world, shards bring good luck. 🍀
Only when you leave/forget items at a campsite or lose it along the way, you must replace it at your own expense. For example, the following items that travellers occasionally lose or leave behind somewhere:
Fuel cap left at gas station while refueling your Spaceship. Please replace it.
Camping chairs left behind at campsite. Please replace 'em.
Part of the cooking gear - pan, collander, cutting board, kitchen knife etc - left behind in kitchen of a holiday park. Please replace it.
Duvet left behind at a campsite. Please replace it.
