There’re so many tip calculators out there for every smartphone, but even though I downloaded one when I got my phone I still just use the calculator on my phone. Most of the time I’m with just Anna or with friends and we’re probably splitting the bill evenly so no major calculations have to be made. I think the only situation where things get sticky is if someone isn’t drinking alcohol or didn’t have much to eat. I wonder how many people out there even know how to calculate percentages?
