This is maybe more an absurdity than a suck. I seem to live in a neighborhood where nobody has a landline. Everyone just uses their cells. The local Dominos is one of the few places that deliver to my neighborhood so they get a lot of calls from us. From our cell phones. Here's the issue. Once you've called from your phone to have food delivered to a particular address, you can NEVER USE THAT PHONE FOR ANOTHER ADDRESS! Not only that but that is the ONLY phone that address can use! So, lets say you're teenage daughter is babysitting and calls for pizza for her and the kids. She uses her cell phone. All is well. Until she tries to order pizza from home and is told that that number is now permanently connected to another address and can only order for that address. Likewise, if the woman who lives at that address should try to order pizza, she will be told it can ONLY be ordered from the babysitters phone. She can no longer use her own phone to order from her own house.
Likewise if a friend comes by and decides they'd like pizza, if they happen to order from their phone you will never be able to order from your own phone again. Every time you want something from Dominos you will have to find your friend and have them call and order for you.
I had guests from out of state recently and stopped them just in time....one of them had her phone out and said "do you have the number for dominos? I'm going to get us some pizza!" I yelled "NO!!!!" because right now mine is the only phone in the house allowed to order for our house and if it's cancelled that's it.
