indeed inconsistency is the problem. using the informal among colleagues at work, and especially with superiors is often the sign of a more relaxed work atmosphere, which is something people want and is thus becoming more common. especially in international companies where multiple languages are used.

there is never a question what to use when i am talking to cashiers, clerks, etc. but when i am at a tech meetup or an informal gathering of people from different companies then the way to address people is very much in question. you never know how people like to be addressed. and while using the formal option may seem like the safe choice, it really isn't because it forces others to be formal with me too, and when i am the only one doing that it puts me into an odd position. the only safe option is to avoid any choice until the other makes their choice.
