Mo'cha Bubble Tea: Discount Layout Confusing

When ringing in an item and applying a discount to it, the layout of the screen can be confusing for some individuals. Applying a discount is done by selecting the discount, but the only way to leave the menu is by selecting the "Cancel" button. Some users may see this as a "Cancel Discount" function.

Suggestion: After a discount is applied, the button re-labels itself to "Done" or add a "Done" button alongside and the cancel button clears out any applied discounts.
