I cannot stand people

Who have no care for others time or space. Like not saying you need to be a mother to everyone around you, but I just walked into a donut shop to get my boyfriend something because he’s having a bad day. This group of like 4 teenage girls with their mother walk in before me and each separately order a coffee and a donut and each time they went up took like 5 minutes to figure out what they wanted. I had to just stand there for I shit you not 15 minutes just to get a single donut and leave. I hate society
