And with this ?

I looooove to play the shopkeeper and what I especially like are the ready-made formulas, because we are made to believe that they are ready-made formulas when in reality they are magic formulas. If so, it's true, you'll see.
As if bewitched by a spell invisible to the naked eye, what do you answer to "and with this?" I can't hear you, but I'm sure of your answer, well you answer "that's all"... you see, it's a magic formula, you haven't been taught it, but you know it all the same .
I then wondered about the origin of magic and I have a few leads to share.
When you decide to become a baker, for example, you go to the CFA, and there, you have the module on sourdough, the module on acidity, how to knead dough, old flours and I'm sure we're told not, but that there is also a module on the baker's formulas so that the magic happens. This is where we teach them to say “and with this” by casting the famous spell that will make us answer stubbornly “that will be all”. But Majax does not only intervene at the baker's, let's take it again.
At the beautician for example, at the aesthetic CFA, we have the module on waxes, the module on the hairs under the skin, that on the cuticles and then, the magic formula dedicated to the beautician. "The nails, we do them rather round or square"? And that's where abracadabra we respond tit for tat "well, round square"...
Finally, I'm thinking of the saleswoman, who also went through her commercial action BTS, learned customer relations, marketing, data management and then vlan, magic option, we also taught her how to spread her powder perlimpinpin saying "Can I help you? » which will necessarily lead to a « No, it's nice I'm watching »…
Despite everything, I found a tradesman who, during his training, certainly didn't have any magic lessons, he was the mechanic, because when he exclaimed "Well my little lady, you have the injector rail which is stuck in the turbo compressor, it has infiltrated the radiator and I'm sorry but we're going to have to change the whole rear-view mirror…” well, nothing ever comes, even on full moon days, no extensive response by the unicorn powder, it is the astral void…
Faced with this negligence, we only have the celestial shield commonly called "cheque book", which even blackened, struggles to replace a magical response that we could shout while fleeing "touch nothing... it will start again tomorrow..."
