It really irritates me when I have a 1:15pm doctor's appointment and I show up on time but they take 45 minutes to take me back to a room and an hour after my scheduled appointment, I still haven't been seen by the damn doctor.......and I have another appointment at 3 that I have to get a ride to and my ride is gonna be at my house at 2:40pm and I am still stuck waiting on this damn doctor!!! Ughh! So irritating.
