BillyBones - a really good question which I think is very relevant to this forum.
Punters are generally looking for a range of services from WL's and obviously not all WL provide all the services.
Most WL's will be upfront regarding some services, such as "Greek". Generally they will be make it very clear whether such a service is/isn't provided. In the case of "Greek", most WL's will send you to a "competitor" if they don't provide that service.
Fair enough - and that's how it should be. If a lady is not into providing a service, she should certainly say so upfront instead of trying to fake it.
Case in point is the GFE. I doubt any WL would send you to a competitor if a punter asked for a GFE or similar. And this is wrong because the punter knows immediately if the WL is not really "into it" - and the whole experience generally turns out to be less than brilliant for both parties. Certainly not a win-win situation.
In day to day business, we all have to turn away work which we either don't want to do, or can't do properly. In such cases, the customer appreciates you telling him/her to go to a competitor where you can get the work done properly.
It should be the same with WL's.
