I just came to a hotel and worked as a receptionist for two days. All their front desk colleagues had endless words, so they got together and chatted loudly.

It is normal for you to be a little unsociable if you are not a particularly familiar person. It is normal for colleagues you know to talk about topics. When you get familiar with them, you will have many topics to talk about. This kind of working atmosphere is actually relatively relaxed, and it will not be so tiring to work.
