Poor punctuation can confuse your customers
As you'll see from this menu I saw at breakfast while I was traveling last week, this diner advertised that I could have Red onion roasted tomatoes as an addition to my omelette. My goodness, did that get my Italian blood flowing. It sounded delicious! Alas, it was not to be. Unfortunately, it was just a left out comma that ruined it for me.
It's a lesson in how important it is for businesses to make sure they proofread their printed materials before making them public. I've seen way too many upscale restaurants misspell such important words as "parmigiana" in their menus.
