Small businesses don’t have time to test too

I just add a small reminder note to myself (it was very cold) and head straight home. Of course, I forgot about that, but a couple of hours later I was looking at the menu online. I was not surprised that hamburger menu is not working correctly on smartphones.
Just take a look at screenshot below:
