What you are doing is not begging, but it is strange to ask for things in this manner, unless you are very close and you would give it back to them or invite them to a similar treat. Otherwise, it is best not to ask them and to refrain from that.

In Islam begging is haram. Right Sheikh? I sometimes give my friends treat. Some time I ask them bro please will you give me treat in restaurant today? Or would you buy me this? Asking like this is ok? Or it w be counted as haram eating?
