With a latte, it’s just normal steamed milk. A cappuccino has foamy steamed milk. Specifically, it has an equal volume of steamed milk and foam taking up space in the cup. You get more actual milk diluting the coffee in a latte, resulting in a milder drink.
This. I worked in a call centre for a while. Service was not the priority, speed was. I got in trouble for staying on the line to actually resolve a customer’s issue because it took a long time (basically ended up having to do a conference call with the third party who had fucked up). I left that job ASAP because fuck that.
