Another webinar?

It's bad enough having to attend teleconference calls and webinars necessary in my own line of work, but yesterday, when I was travelling home from Worcester, I was a reluctant and uninvited guest at someone else's. After half an hour of sitting behind them without commenting, I simply  had to say something when they answered a telephone call on a different device so their webinar continued unobserved. Apparently the attendee didn't have any ear phones and obviously didn't want to buy any from the on-board shop. I wasn’t impressed by the unprofessionalism of staff working for a low-end clothing chain
