Don't you think... this is unfair on others who cannot offer tips???

Mohammed800 correctly said.... You do not need a service to give Tip.

In addition..... yes,... give someone who watering the landscape in hot weather... the paper seller at signals... even you can give at petrol pumps...

My point is... He should do his job with what he agreed with his employer.

In addition, I would like to highlight which you all might not aware.

Some of the employers, keep a box Back Room of the shop. Once waiter get tips, he should deposit there.

End of the day employer will count ALONE and give certain potion to each.

Allah knows, whether something going to Employers pocket too.
