I tell people to ask first before calling, because it's just polite. otherwise they may not get a response

the only people who can call without notice are my boss and the owner, and even then, if you want me in a good mood and to be prepared for whatever project you're gonna ask about that I haven't thought about in months, it'll go better if you just ask if I have time to talk about xyz

some people don't get it. and those people get to sit there on the line while I bring up the project files in silence

"can I just tell you what's going on-"

"no. because then I'll have questions about your shitty description. so we're gonna wait here until I have the information open for what you're asking about so we're not playing tag later"
