Earlier today I spent about five minutes loitering near a busy intersection swiping ineptly at a Kanghaskan. Felt like a total dweeb but it was definitely worth it!

I realised pretty quickly that timing your swipe is probably the most important part. If you can get that right, you've got a much wider margin of error available. That's important if you've got stubby, comically inept fingers (like I do)!
