These might not be the exact reasons, but I want to point out some of the advantages of this design:-
1. These stirrers were designed keeping in mind the "on the go" customers, these customers don't have time to sit and have their coffee, they are either getting late for work or are just looking to grab some breakfast and coffee on their way to get somewhere and it becomes difficult to drink coffee while you are walking or running, chances are that they might spill the hot coffee, which may or may not cause burns, but will surly leave a coffee stain, keeping this problem in mind the designers must have designed the stirrers to serve as a straw as well.
2. The size of the holes might be intentionally designed smaller so that the customer can have the exact quantity of liquid as he/she would have taken in one sip from the cup, as we tend to take smaller sips of hot beverages as opposed to colder beverages, which also makes sure that he/she doesn't burn his/her tongue,
3. This design also helps the coffee house save the cost of providing extra straws in addition to the stirrers, since these straws would have to be made from high quality thermosetting plastic as opposed to the normal straws which are designed keeping only cold beverages in mind, hot beverages like coffee would cause the plastic straw to bend, de-shape or even melt,but as stirrers already are made of thermosetting plastic and can tolerate high temperatures and still maintain its shape,all they had to do is Make some holes,
4.Not to forget all the plastic they save from making the stirrer hollow .
5. This design also provides added strength to the stirrer as strength to weight ratio is better for a hollow pipe than a solid rod.
So all in all this is a much more useful design as compared to the normal stirrer without any holes and I have to say that it is a rather ingenious design.simple yet brilliant design.
