Your loss, bitches.
Me: Hello. Do you have any of those compressed gas bulbs you use to make whipped cream?
Customer Service Technician In Large Sydney Road Catering Supplies Outlet [beaming in bland, vacant customer-servicery way]: Yes; yes, we do. One of our most popular consumables. Right over there. [indicates stock stand groaning under the weight of vast supplies of nitrous oxide bulbs]
~: Tell me, do you get a high volume of well dodgy-looking tweakers like us, who probably aren’t actually employed in the catering industry at all, coming in and stocking up on massive quantities of these?
Customer Service Technician [absolutely without missing a beat]: Yes; yes, we do.
(And to that small handful of priveliged people who are coming tonight – see you soon; looking forward to it.)
