Okay, So: There's A Local Restaurant Whose Online Ordering Process Involves Various Selecting Various

Okay, so: there's a local restaurant whose online ordering process involves various selecting various sauces to be included with one's order – so many units of teriyaki sauce, so many units of hot sauce, so may units of peanut sauce, and so forth.

The idea is supposed to be that you can select any combination of sauces you want, as long as it adds up to no more than four units. However, what the app actually required is that you select exactly four units of sauces; it wouldn't let you submit the ordering form if the total wasn't exactly four.

Just today I discovered that they seem to have fixed it... not by correcting the errant validation rule, but by adding a "no sauce" option, which counts toward the required total of four.

Thus, it's now possible to place an order with, say, two units of teriyaki sauce rather than four by entering 2x "teriyaki sauce" and 2x "no sauce". Similarly, an order with no sauce at all is 4x "no sauce".

This is quite possibly the least intuitive ordering process I've ever encountered, and I've literally worked in e-commerce.
