Does providing the person you are supposed to honor, such as one's father and Rebbi, the opportunity to do a mitzvah in a more mihudar way at the expense of your own hiddur fall under what is required under the laws of honoring?
Imagine the following situation:
The person who you must honor asks you to pick up a Lulav set while you are shopping for your own. They give the money for it. Now, at the shop/stand you find the two sets you are going to buy. One for you, one for him. Both are completely kosher and both are mihuddar. However one is somewhat nicer under the guidelines of hiddur. Who should you get the nicer one for? Yourself, or the person you need to give honor to?
