WHY are there two straws added to cocktails?

 Numerous theories have been made about this. The following are the top three theories:

1 To make drinking multiple-layered cocktails more convenient without blending the layers. Due to the fact that one straw sinks to the bottom of the alcohol, it is significantly longer than the other.

2 To make the drink simpler to stir, a few straws are added.

3 The cocktail can be sipped by two individuals using the straws, and it looks really romantic.
