One recurring theme at work is people wanting us to fix their bike, essentially for free. Sometimes they've bought a real clunker at the local car boot sale, and they lug it into the shop in the hope that I'll "Make it work better" which probably means replace the cables, true the wheels, fix the brakes (including new blocks) and rebuild the lighting.
These are fairly easy to deal with; I give them a cost estimate and they leave in a huff because "the last mechanic did it for 10€".
More difficult are clients, or former clients who think that because they were/are clients, I'm their on call free bike mechanic.
Secondly, not all speak German, and certain individuals are remarkably persistently unable to understand "no". Asking a client of the same nationality to translate can help, but if we do this too often the translators understandably get a bit fed up, especially if they end up in the middle of an argument.
Today was a classic. a former client turns up with what was a very good quality bike. The bikes main problem is neglect but it's also badly damaged; the rear wheel won't turn, light smashed, mudguard flapping in the breeze. He wants the wheel repaired. The wheel is what we in the trade technically call "gerfürkled"; I've seen straighter pretzels. I'm not supposed to do repairs, but for clients we are allowed a bit of leeway, after all who else is going to help them? However we're strict that there's no discount on our usual rates, (which are well below the norm). I also have no translators today; my boss speaks the same language but she's out of the building.
I tell him I'll replace the wheel, it'll be quicker than the long discussion if I say no. The cost is 10€ for the wheel, and 6€ for ten minutes work. If it gets complicated I may take 20 minutes so it'll be 12 € Okay, he agrees.
I take his bike into the workshop. he wanders in. I shoo him out again as it's not a public area.
After some digging I find a serviceable rear wheel (note to self, need more wheels). There are complications; the last wheel wasn't even in straight, so I have to reset the brakes and gears, By the time I've sorted it to a ridable state, it's nearer thirty minutes but I overlook that. Return bike to customer.
"Light kaput. Mudguard Kaput. Needs fixing."
This is common; people ask for one repair then claim they thought everything would get fixed for that price and try to pressure me to do the extra. I expect this is because in their home culture, this would be expected. However, they aren't in their home culture.
I explain this will cost more: I can sell him the light for 10€ and fitting it costs 6€. I'm not touching the mudguard because it'll take hours. Offer to sell him the light and he can fit it. He isn't happy but wanders off to the till with the light.
Ten minutes later he's back, in the workshop, badgering one of my clients. He doesn't know how to fit the light. Can we do it? Again, this is a tactic I've seen before. I Explain that fitting the light is more expensive. He still wants me to do it. Much discussion.
Fit light, hallelujah, it worked first time, change the bill to reflect this extra. Show customer. He's not happy. Why does it cost so much? Explain;
Wheel: 10€,
light: 10€,
Time 3x10 minutes = 3x6 =18€
He complains "so expensive, so expensive, why so expensive?" I explain the bill again. He repeats "So expensive, why?", hoping I'll lower the cost. I don't, because I know if I do he'll expect me to repair something else next week for even less. Instead I explain the bill again. He's not a happy customer. I go with him to the till so he won't try and nag the till staff for a reduction.
I'm hoping this will be effective long term and he'll not come back looking for free repairs...
