Random incident: Teacher to teach what?!

Sitting at a local cafe in Baku and working. After a while a group of ladies ( two moms and two daughters) came into the cafe which was amazingly full. As soon as entered they approached to a table of four which was already "marked" with two coats. They made themselves comfortable without paying attention to the fact that this table is someone's and that someone's coat is still here. 

In a minute the couple who were probably at the bathroom came back. They apologized and took their coats off and turned to the waitress to ask for another seat. These ladies did not even move or apologize. In couple of minutes they realized that this table is too much centered and that people passing by all the time are making it hard to have private conversation. 

They stood up and moved their things to find a new seat. As I was sitting at the table of four (i know is wrong but I was sitting there with four people since morning) they started approaching me. Already agitated from the incident with young couple I did not raise my head. Waiter decided to mediate for them so he asked if it would be ok for these ladies to sit next to me. I said yes and went on with my work. They kept loudly arguing on what they want and what they should not order. One of the ladies called someone and asked if he/she feels confident to take his/her exam tomorrow. If not, she said she will call the dean and ask to give free mark. Looking like a classic rüşvətxor müəllimə  i got irritated even more by her physique. One of the girls looked embarrassed at all times and kept asking others to behave. Apparently, she was the most educated among them.

After discussing everything on the menu she ordered tea. One of the women said that she has some qənd and that they should not buy sweets. While involuntarily listening to their conversations, my food arrived. I eat my food and asked for the bill. As soon as I paid for it, I stood up, packed my stuff to slowly move out. In the meantime one of the ladies was picking her tooth with a tooth pic and as soon as she was over, she tossed it my side of the table. I looked at her in disgust and left immediately. While I was making my way out, they were loudly chuckling.

While walking I thought, if a teacher of this nation can not even behave herself in a public place, how does she behave in a classroom where she needs to be an example?!
