man i've been in that same situation. I had some bitchy managers where I worked and I called in sick one day then worked the next day because it was only a 5 hour shift then the next day i had a 9 hour shift and i felt really sick so i called in and she got pissed and said i didn't even sound sick and if i wanted to work there anymore that I'd have to bring a doctors excuse. I was like "wtf?" its a sunday, most family doctors are home for the weekend. The only way i'd get a doctors excuse would be to go to the hospital, why the hell am i gonna go to the er if i just have the flu or something. plus i mean i had plenty of sick time saved up because i rarely called in. Anyway, she bitched at me the next day when i came in i just kind of ignored her and she tried to mention it but i never did bring one in. Guess they forgot about it.
