Mrs. Shannon has identified 10 available class times for the summer of 2022. Ten class times is a tiny fraction of the number of people that are interested in signing up for lessons. Regretfully, it is not a possibility to provide services for all interested swimmers. To mitigate the frenzy of registration, Mrs. Shannon releases class availability in tiers. Tier 1 consists of returning customers. In the event that returning customers opt out of lessons, registration availability is then sent to potential clients. Mrs. Shannon genuinely appreciates your understanding and support of this necessary process.
