Hi this is Carmen,
I have been very carefull but still I have walked into it with open eyes, YES custumers are nice, but some of those people out there you have to be carefull with.
I had a landlord walked out on me with my money and deposit, and I had a client taking my friends money and telephone using violence in the appartement I shared with her.
I also try not to work after 11:00 pm, but also in the daytime things can happen.
