Changes with Technology!

I have been a waitress since i was eighteen years old and i actually really enjoy it and enjoy the people i work with, but for some reason I'm not very good at ringing alcohol drinks in and i seem to screw them up every time.  The Apple Corporation keeps on changing the drinks on our menu and we are at about 2,000 drinks that we can make and it can sometimes be overwhelming when everyone at the table is talking at once and the noise level in through the roof and theirs people walking into.you.  The technology that i would love to adopt that would make my waitress life way easier is a key pad at all the tables and the guests could type in what they want for a drink, whether it be an alcoholic drink or non-alcoholic drink.  Then i would not have to worry about taking five minutes to ring in one tables drink orders.  I think that we as waiters and waitresses would be able to rotate our tables faster, thus making us more money in the end.  That probably sounds really greedy, but that is how we make our money.  The faster when rotate your tables the faster you will get sat again .  I think that their could be a few barriers and obstacles that the restaurant industry would face if we put this technology on all of our tables.  First the costumers would need to know how to use the pad.  Hopefully they could make it in alphabetical order so it would be easy to understand and access at the tables.  Secondly, maybe people enjoy the interaction with a waiter or waitress to order drinks, so when they ring in the wrong thing or don't like it they have some to yell at or blame (hahahaha).  Something that might hurt us is that the customer might not want to tip us more since we didn't take their drink order, but with the key pad we would still serve them the drink, they wouldn't get it themselves. I might cost a little to put them in, but in the end i think it would make our life a lot easier and less stressful, thus giving the table and people better service.
