How do I get a word in edgewise? [View all]

There are many people who I have to talk to for various reasons but they're impossible to talk to because they never let me finish a sentence of more than three words.

Examples;

I've got a burned out speedometer light on my dash, so I buy the bulb they told me to buy (but I suspect it's actually the odometer light). My ABS is acting up so that dash light is on and it is the right bulb, so I attempt to explain ti the mechanic that the speedometer light is out, I have a bulb but I think it's the wrong one, so if it is, steal the ABS light and use that. He interrupts as soon as he hears that I've git a bulb, saying "so you want me to replace that bulb", then he finally gets it that I want a different bulb replaced, as soon as he hears "ABS" he wants to replace that, so I try a third time. It comes back from the shop with the odometer light replaced, no speedometer light and two others not working.

Tonight I have to explsin to somebody that they have to register to park, no I cannot do anything aboit their old ticket because I don't have the software, and if they're going to be there that often, they should apply to be on the whitelist. Nothing doing. Interrtion after interruption after interruption.

Earlirr tonight I'm explaining that yes, I will hire her friend to do my back yard but I need to be there, yes she can have some paving stones, but the square ones not the curvy ones as I need them. Nothing doing. I get three words out, she's talking again.

Ideas?
