You should make an appointment! is better!!
It depends. Usually ppl go in faster by appointments. Or by weekdayds but you gotta be there before or around 7 am.they form a line so if your in the ratw of first 15 to 30 ppl in that line ylu can get in and out by 8.30 depending on the issue you need to fix. But being early there is always the best idea to get our fast
