The Interface of Restaurant Receipts
It happens. You get handed the credit card receipt at the end of the night, your date waiting across from you, and have to shuffle through the multiple copies of the receipt to find the one your need to sign. Yellow is merchant, white is customer? White is merchant, yellow is customer? What’s the third one doing there anyway? You hurriedly sign one, sweating over tip and total, only to find the waiter tapping your shoulder asking for you to sign the other one.
Okay, it’s not normally that bad. Unless your date is tapping-her-foot impatient. But I know that I’ve signed the wrong one on a couple occasions, and I have to think about which one to sign on most occasions. In fact, when I’m paying at the counter, the clerk will almost always point out which copy I have to sign as I hesitate.
Is there a way to make this better — making it so simple that I don’t have to think, and that clerks don’t need to help their customers sign the right thing? Bigger typography and better explanations? Nobody reads those anyway. How can we fix it?
I restaurant I went to today had a great little hack that made it totally obvious. It took me a bit to realize that I hadn’t even hesitated during the signing process. Their solution was simple: just wrapping my copies of the reciept — the things I didn’t need to sign — around my credit card. The receipt I needed to sign had the right affordances: next to the pen, laid out flat, begging to be signed. The receipts I didn’t need to sign also had the right affordances: they were wrapped around an object destined to go back in my wallet.
It’s an excellent interface, and a great example of physical mistake proofing and poka-yoke. When I think back, there are other restaurants that do this too. I never noticed because it “just worked”. It was invisible — just like a great interface should be.
What examples of this kind of everyday, physical interface improvements have other people noticed?
