What fees did I incur during my visit to Kamphaengphet Immigration?

Went to Kamphaengphet Immigration and what a pleasant surprise it was, pretty much a brand new site, and extremely helpful staff, went armed with 2x photos/photo copies of passport pages/60 day tr evisa/ they didn’t want my copies and did it themselves and only took one of of my passport photographs, luckily I had my Thai g/f with me and the accommodation /place of stay question was sorted, had to pay 1000 bht along with the 1900 bht,. Not 100% sure what the extra 1000 bht was for ?,. I’ve been in loads of hotels over the last 50 days, and been staying at g/fs house on and off over the last few weeks, went in at 2.30 pm and came out at 3.30 pm,. All done, very quiete only about 8/10 people plus me and one more “ Farrang”,. Brilliant main man immigration officer, very nice man and all his staff members great to, . Lucky to be close to this office,.
