Here’s a recent email I sent this morning to a contact I have who works in the technology department of a large barter exchange.
How about a tax/tip calculator for folks going to restaurants that accept scrip? They could enter the food total, the amount of the tax, then the app could tell them the total amount of scrip and cash they should leave to cover tax/tip. You could even give two options for when the food total is in the awkward “in between” amounts. For example:
Food Total = $25
Tax = $5

Round Down Option
Scrip = Food Total rounded down = $20
Cash = tax + amount rounded down + 15% of (Food Total + Tax) = 5 + 5 + 4.50 = $14.50
Round Up Option
Scrip = Food Total rounded up = $30
Cash = tax + 15% of (Food Total + Tax) = 5+ 4.50 = $9.50
I think most people mean to leave tax and a good tip when they go out, but the calculations are difficult to work out sometimes. This could be very helpful in keeping restaurants happy members and make life simpler for members as well.
