I have a WooCommerce store specialized in renting out beach equipment. I added a dropdown menu to the checkout page where a customer can select for the order to be delivered or that they can pick it up themselves. If they select the delivery option, a $10 fee is added to the cart total, listed as Delivery Fee. If they select pickup, a second dropdown appears where they can select a pickup location. I want to add the option for clients to purchase cold drinks from the checkout page if they select a specific pickup location (Kamini's Kitchen), the list of which should pop up when they select this one pickup location. I wrote it so that checkboxes appear for each drink and a quantity that can be selected. When a drink is added, it should be added to the cart under its proper name and the listed price should be added to the total (times the multiplier). Lastly, the selected drink options should appear in the order e-mails and on the admin backend.
Here is my code attempt based on this answer thread:

But when customer select an optional drink from the list, the additional related fee get not added: The checkout get refreshed but nothing gets added. Here the "drinks" part is not working as intended. In my code, I have defined an array of all drinks with the label name and the cost for each option, and this drinks options list appear conditionally based on the selected pickup location via JavaScript. Here, I'm stuck with the part where the selected options are supposed to be added to the cart dynamically via AJAX.
Ther are multiple mistakes, unnecessary and missing things in your PHP and jQuery code.
As you are storing the selected fields values via Ajax in WC Session variables, don't use PHP $_POST to retreive the data outside PHP Ajax receiver functions. Use the WC Sessions variables to get the selected values for the dynamic calculated fee, and to save those selected values as custom order metadata.
Try the following instead:
// Utility function: Remove custom WC Session Variables
