One of the worst airport experiences I've made so ...

One of the worst airport experiences I've made so far. I was at Beijing airport for a layover only (VIE - BKK). They make you "enter" China so that they can check your passports and hand luggage once again. The waiting lines are really long and the counters are ridiculously understaffed. We waited for a VERY long time, had to go through crappy metal detectors that were overly sensitive (it beeped with literally everyone). The guy who checked my passport must have been in some sort of a coma. He needed five(!) minutes to let me pass even though there were hundreds of people waiting behind me. When you're done with this tedious procedure, you don't really find any options for getting a snack/drinks. We found ourselves in front of a coffee shop stand that charged us horrendous prices for a simple coffee. Then our flight was delayed. No one would give out information as to why that happened. Plus, it was extremely cold (were there in December). Would avoid this airport at all costs!!
