Final answer:
Towel buckets in high-usage environments should be checked at least every hour to maintain cleanliness and availability.
Step-by-step explanation:
When working in environments where towels are used frequently, such as a gym or spa, it is important to check towel buckets at regular intervals to ensure cleanliness and availability. The frequency at which towel buckets should be checked can vary depending on the specific protocols of an establishment.
However, a common standard for checking them is every hour. This ensures that used towels are removed promptly, and clean towels are always available for use. By maintaining regular checks, businesses can provide a high level of service and uphold hygiene standards.
