Hotel Baths and the importance of client contracts

What is it with American Hotels in their competition to create large rooms with tiny baths. I've been in loads of Hotels and practically none of them in the US have a bath that is worth of the name "large sink" would describe most of them.

This is a cracking example of why a simple service definition isn't enough to ensure a decent quality of service. After all a bath is something that holds water, in which you can sit down, so these enlarged sinks match the basic criteria. They hold water, and if I get in one I get wet.

Now if when I specific a hotel room I could say

Bath.length > 1.2m
Bath.depth > 50cm

Thus giving a detail precondition on what I consider most important in a hotel room. I could also specify the details on the gym, to make sure its not just two crap machines in a tiny room.

Effectively here I talking about the importance of preconditions from a client perspective when selecting and invoking a service. A more business analogy would be when thinking about acceptable response times for a service, where if they don't respond in time you don't care about the result. Its about how the client can place restrictions and contracts onto the service.

The normal way to do this is via parameters on a method, but a more effective way would be via a contract applied to the call which could be managed as a policy independently of the invocation, i.e. changing acceptable response times.

Thus invocations should be about a negotiation between client and service to determine if the required conditions and QoS can be met, if they can't then the invocation is invalid, something the client should have as much say in as the service.

Seriously though, what is with US hotels? The beds are huge, the baths are tiny.

This chimes with my earlier post on Bathroom Interoperability. See also Phil Wainewright's response.

Well, basically you are just saying that a hotel room with a bath is not enough. You underspecified your requirements, because bath is a too general term. Instead of adding preconditions you should detail your requirements more and define what kind of capability you are really expecting.

Is it that Americans sleep mor often than they bathe?

It's because most Americans take showers not baths. Baths are for lazy people who have nothing better to do ;)
