It's ridiculous to me how persistently poor receipt usability is. At a minimum, this is how I would like to see my ideal receipt:<p>* Sales tax integrated into the dish price rather than a sum at the end (or if this is not possible, at least an indicator of what the local sales tax rate is on the receipt)<p>* Items split up into categories: drinks, apps, mains etc.<p>* A percentage tip guide on both the receipt & the credit card statement (ie: 15% = $3.45, 18% = ...)<p>* A form area on the back for writing out how to split across multiple credit cards<p>* menu prices engineered towards nice round numbers post-tip (if I get a $51 bill, I'm inclined to tip $9 to make it an even $60. If I get a $52 bill, I'm inclined to tip $8 to make it an even $60).<p>At most, I've seen 2 of these features on any one receipt, most receipts have 0.<p>I think the most trying use case receipt usability needs to accommodate for is the birthday scenario:<p>A group of 7 people are celebrating someone's birthday. They order drinks, apps for the table to share, everyone has a main course and 3 people have desserts. The cost of the birthday boy's meal is being split among the rest of them. there are 2 couples who are paying jointly & 3 singletons.<p>Such a scenario is never going to be trivial but it could be a hell of a lot less painful than it is currently.
