So we were in this restaurant... great food, dim lighting, menu with entrees listed in 8-pt. font. At least, that's my best guess, as all I can see is something that looks like this. I retrieve my 1.50 reading glasses from my purse, but they are not enough. So I unzip the side pocket and get out my back-up pair of reading glasses and put them on ON TOP OF the other pair and hold my cell phone toward the menu as a faux flashlight just about the time the waiter arrived at the table.
I now have an emergency pair of "dark restaurant, small-font menu, 2.5 strength, because-I-don't-want-to-be-embarrassed" reading glasses with me at all times.
