The unscrupulous can be found most anywhere in the world.
As stella says, this was no mistake :-(
There are people that think that ripping off others is acceptable.
It is imperative that all consumers/customers on aruba and/or at restaurants in your own hometown to be your own advocate.
Check your ticket to see the charge, the tax and the tip if added in.
If it does not seem right, question it and if the answer is still not the answer that makes sense to you, bring it to the next level of management.
I am sure Amsterdam Manor food and beverage director would not be happy with this negative publicity.
But, it is what it is and maybe that server that made the "rip off" will be held accountable.
disclosure..........my husband and i frequent Amsterdam Manor's beach Bar, Pool Bar and on occasion their restaurant MANGO.
We like the service and products.
We typically are customers at one of their bars at least 5 times per 14 day vacation.
