Welcome to this message board! You don't apologize for dumping here. This is what this place is for. In fact, it is almost a requirement!
You have really had some experiences in this area. Maybe sometime you will be able to help me.
I find that timing is a problem here as well. They are always encouraging me to come early - my scheduled time is 11.00 a.m. But somehow even if I am there at that time, I don't go on until 11.30. One day, I decided to go at 10.45. What time did I go on? 11.30.
Thank goodness, I drive myself, so there is no waiting after.
