A lot of countries (e.g. UK) seem not to have the clear B1/B2 separation that the US has with just a "standard" visa for US citizens and others covering routine business matters like attending conferences, meeting with customers, doing some work in your hotel room, etc. in addition to tourism stuff.

But you're right. No one really wants to hear about your travel expenses being covered or your nominal honorarium--which are absolutely routine for certain types of industry roles. Your company is covering it as a routine matter (and that applies if you're in business for yourself as well.)
