Absolutely. If you happen not to have an appointment, you'd face long waiting hours ahead of you. Also, time frame varies depending on the kind of service you need.
Yes. I definitely recommend you make an appointment do you don't have to wait there all day to get seen. I had to go back another day to purchase 2 tablets because they didn't have an open slot until 5:00pm and it was only 1:15pm.
