Having a calculator to calculate change in this application is weird

This app is to manage customer's membership details on a desktop, not a cash register;
irrelevant feature

You can use it to calculate the leftover reward points after claiming multiple vouchers, or any other tasks that require calculation.

❓ Issue response

Team chose [response.Rejected]

• I disagree

Reason for disagreement: The developers' response highlights possible uses for a calculator, but not the issue of whether this app needs the calculator. I feel this app does not need one, again because the main purpose of the app was supposed to be for "managing bubble tea shop customers’ membership details". It is especially unnecessary considering calculator apps are already commonplace on computers. The current calculator is also fairly lacking in utility compared to other calculators. For example, entering 2 * 2 + 3 = returns the result of 2+3 which is 5, whereas other calculators would give 7.

The time spent on implementing the calculator feature ought to have been spent on other more useful features for this app, such as being able to sort the customer list by the different fields, or saving the command history and allowing scrolling through them using the up and down keys

❓ Issue severity

Team chose [severity.VeryLow]
Originally [severity.Low]

• I disagree

Reason for disagreement: This issue is not a cosmetic issue as it concerns how the target user is supposed to utilise the app. This calculator serves little benefit to the user as compared to other features that could have been implemented instead using the time spent
