On the specific case of the flags, I asked at the receptionist, who in turn called the manager. Within minutes, he was there to talk to me. Doubtless perplexed by my question as to what informs the kind of flags that the hotel hoists, he still tried to proffer an answer.
His explanation--in sum--was that they hoist flags of "constituencies"[my words] that are likely to visit the hotel. So the EU, US, Ghanaian, Canadian flags they fly suggest that clientele from those countries are free (and likely) to visit the hotel.
I cannot help but wonder whether it would not make good business sense--even--to hoist both an AU and ECOWAS flag--given that the latter hosts many conferences at hotels round the capital?
Beyond the fact that it is serious food for thought, I think there's merit in sending a questionnaire, perhaps arranging for an interview(maybe even an email one) as to why the state of non-flying AU and ECOWAS flags is the case.
