Gulf Air's biggest service problem, let's face it, is that they have to employ male Bahraini cabin staff.
The vast majority of these guys (and there are some exceptions) are not service-oriented and although efficient, there is none of the friendliness that passengers enjoy with other airlines.
And trying to get a glass of wine!! Well, I know Bahrain is a Muslim country, but if they do not want to serve alcohol to pasengers then they shouldn't be doing the job.
