Ah, yes, I can imagine in such a customer service interaction the one being paid to do it all the time may not mind it lasting as long, or at least there may be a discrepancy in preference. I've been texting with someone over Whatsapp and she seems to treat it more like email: no read indicators, no set response time (sometimes minutes, days, or weeks), longer responses when she does. It can be so hard for me as I associate WhatsApp and texting with relatively real-time chat and the differences in expectations have caused conflict between us quite a few times.
