By your reasoning, would it be possible for a person to make herself a cup of coffee and drink it without you considering it to be ritually?
Making coffee is much more susceptible to this kind of ritualmaking because of the implicit repetition, sequence and waiting qualities of the process. That said, there are people who engage with the process without any ritual - the patient in the dentist's waiting room who pops in a K-cup, the McDonalds worker who fills the McCafe order off a ticket, the spouse who runs out of tea and puts on a cup of their partner's coffee.
