Fellow blogger mdx found this sign on Portland blog Potato Gun. According to the post, if you want to buy some fruit at this produce stand, you calculate your own tab and just leave some money in the box. It's all about trust, which is ironic, considering I find it hard to trust anyone who spells PlEASE with the offending lowercase L, not once, but twice in the same sign.
The word PlEASE is fast becoming the most popular observed and noted violation in the lowercase L world. Perhaps this is due to the fact that, when people write signs, they are generally trying to be polite, so they use the word PlEASE a lot. Anyhow, I've posted the photo to the left as an example of a lowercase L sighting that does not truly qualify as an offense. Observe that, while all the letters are uppercase except for the lowercase L, the L stands taller than the rest of the letters, and is therefore unlikely to be confused with an uppercase i.
So from now on, all qualifying lowercase L's should be roughly the same height as their surrounding uppercase letters. Like mdx's find, which is perfect.
