A couple of discussions recently have led me to ask: can an EC perform the 'bait and switch' scam on a customer?

I'm thinking of the situation where, for example, the customer plans to build a laundromat; absent specific plans, the EC submits a bare-bones quote, with just a few receptacles and minimal lighting. Everything sails through plan check - then the customer suddenly figures out that the design is inadequate.

Sure, the EC says ... but that's extra.

IMO, this is an unethical practice. The EC has made his price appear 'low' as compared to anyone who bid assuming a reasonable installation. With the 'change orders,' the 'cheap' guy suddenly isn't such a bargain.

What do you think?
