Final answer:
Standard custard cone sizes usually include Single Scoop, Double Scoop, and Triple Scoop. The 'kid scoop' is not commonly considered a standard size.
Step-by-step explanation:
When considering the sizes of custard cones served at an establishment, it is important to recognize the options typically offered. Based on standard options available in many ice cream or custard shops, it is common to find the following sizes:
- Single Scoop
- Double Scoop
- Triple Scoop
Therefore, the standard sizes of custard cones that are served would include the Single Scoop, Double Scoop, and the Triple Scoop. The 'kid scoop' may not be universally recognized as a standard size, although some shops might offer it as a smaller option for children. However, this option is not typically considered a standard size when compared to single, double, or triple scoops.
