@Inna22 Well, you were obviously trying to poison your guest but she was too clever and foiled your plan 🙂
Yes, it could definitely be a fitting symbol of the current guest demographic. I'm surprised she didn't call Airbnb to report it and demand a full refund. I imagine she'll be sure to mention it in the review.
Expiry dates aren't that serious anyway. They are always earlier than the stuff is really good for, to cover the company's a**. A nurse friend told me there's not even anything dangerous about taking expired medication- it's just that it might not be as effective, having lost some of its potency.
About a year ago I found a bottle of organic apple juice in the back of my pantry that was 7 years past the expiry date. I opened it, the lid made that popping sound to indicate it had been well-sealed, I took a sip, waited awhile to see if it made me feel sick, and when it didn't, I drank the whole bottle. It was fine. You can tell your guest that.
Speaking of cookies, I've always been banboozled when looking at the ingredient list to see "coloring" listed. What color could cookies be if they didn't add coloring?
