Get a big watch with massive numbers.

Never let clients see the labelling- 'trim' (tiny)
on the condom you've picked for them

It is good to have on stand by latex gloves for dirty finger nails etc.

Never leave all your clean towels in the shower room, I give them 1 clean towel or you'll end up like their wives doing their laundry x

Have a cheap handy clock e.g. ?2 Asda one in a prominent place easy for you to check the time without looking too obvious - but make sure it doesn't have a loud tick!  Or it sounds like we can't wait to get rid of them.

Also try not to talk about yourself too much - I am still crap at this lol.

I think I talk out of nerves or to break the ice.  Try not to overwhelm them with too much prattle or on the other hand too little everyday talk may seem clinical.

Money upfront, always check your condom/lube stash, don't fall for a client, never think of it as a lifestyle - it's a job nothing more, don't be intimidated, save as much as you can, know when it's time to get out of the business.

For that matter, never leave anything in the shower room that you don't want poured down the drain. You can have a very obvious bottle of shower gel right there by the shower and they'll go to the far corner of the bathroom to find the most expensive thing you have - something that smells like flowers or perhaps even a bottle of eye makeup remover - and use that, instead.

Off the top of my head..

? Use an iPad as a clock - helps when you are a bit blind as the glowing numbers stand out more!
? Hibiscrub as a substitute for shower gel
? water based lube for pussy & silicone based lube for anal
? No matter how long you have douched for, that anal cavity always needs a bit more
? gloves/finger stalls for fingering
? incense for clearing that sex room funk
? candles for same reason, preferably those yankee candle tartlets
? minty shower gel
? tinted lip tint instead of lipstick to avoid looking like The Joker
? king size fleece over the bed with towel over the top of that for those shitty arses
? Mac Prep & Prime before retouching makeup & after to set
? vanilla essential oil in diffuser water
? condoms over toys
